ARLP019 Propagation

SB PROP @ ARL $ARLP019

ARLP019 Propagation de K7RA

ZCZC AP19

QST de W1AW

Propagation Forecast Bulletin 19 ARLP019

From Tad Cook, K7RA

Seattle, WA May 10, 2013

To all radio amateurs

SB PROP ARL ARLP019

ARLP019 Propagation de K7RA

Average daily sunspot numbers remained about the same this week,

with the number nudging up from 120.9 to 121.7. The average of the

daily solar flux numbers went from 136.5 to 137.5.

An odd thing happened too. For two weeks in a row the average

planetary A index was the same as the mid-latitude A index. Last

week they were both 9.9, and this week both values were 8.

Predicted solar flux for the near future is 125 on May 10, 115 on

May 11-13, 110 on May 14, 105 on May 15-16, 110 on May 17, 120 on

May 18, 130 on May 19-20, 135 on May 21-22, then rising to 160 on

May 28.

Predicted planetary A index is 5 on May 10-11, 8 on May 12-13, 5 on

May 14-20, then 15, 10 and 15 on May 21-23, 5 on May 24-27 and 15

and 10 on May 28-29.

F.K. Janda, OK1HH predicts the geomagnetic field will be quiet to

unsettled on May 10, quiet to active May 11-12, and quiet to

unsettled May 13-19.

The forecasts from OK1HH have been getting shorter. At first the

text was shorter because there was less variation over the forecast

period. So instead of shifting between five different levels of

activity over the course of nearly four weeks, we've seen two

levels, as in this week's forecast.

When I checked every bulletin since the first of the year, I found

that the number of days the forecast covers varied. The first two

bulletins of 2013 each covered 23 days, the next was 25 days, then

the fourth bulletin was 23 days, followed by 24 days on each of the

next three. The eighth (Propagation Forecast Bulletin ARLP008)

covered just 17 days, and the next six weeks varied from 21-24 days.

For bulletins ARLP014 through ARLP019 (this bulletin) the coverage

was 23, 19, 25, 24, 17 and 10 days. So the predictions for this

bulletin and the previous two all end on the same date, May 19. I

will see if I can find out what his methods are, and if perhaps

variation in conditions leading up the date of the forecast in some

way limits the number of days that are predicted.

At 0119 UTC today (May 10) I received an alert from

http://SpaceWeatherLive.com (not to be confused with

http://spaceweather.com). The message is in Dutch, and it looks like

it says there was a "Class M3.95" solar flare. But the message does

not say whether the flare was geo-effective (Earth directed) or how

long it lasted.

I note that http://spaceweather.com says the flare was just over the

Sun's eastern horizon, so it was not aimed at Earth, but it will

move toward Earth "in the days ahead." An event at the eastern

horizon should take about a week to move into a position where it is

aimed toward Earth, although another variable is the latitude of the

region.

The English version of their web site is

http://www.spaceweatherlive.com/en. In the group of six graphs at

the top, five of them cover the previous two hours, and the Kp Index

covers the previous 24 hours.

At the bottom of the page is a flattened version of the STEREO image

at http://stereo.gsfc.nasa.gov/. Instead of watching the rotating

globe, you see all sides of the sun at once.

David Moore sent a link to Phil Plait's "Bad Astronomy" blog (see

http://www.slate.com/blogs/bad_astronomy/2013/05/08/solar_eruption_different_spacecraft_see_a_solar_eruption_from_different.html)

with an article and an impressive NASA video showing a May 1 solar

event, as seen from SOHO, SDO and STEREO. You can see Phil's website

at http://www.badastronomy.com/index.html. Bad Astronomy refers to

Phil's attempts to correct popular misconceptions about science.

Lance Collister, W7GJ of Frenchtown, Montana wrote about recent

6-meter adventures: "Well, I think the SFI being over 145 on

Saturday May 4 probably moved the TEP further north than usual - and

with the early onset of Es, which just happened to connect me to

Texas just at the right time of late afternoon - I got my first

ionospheric link to South America on TEP this cycle. Saturday I

completed CW contacts with CX3AN, LW3EX, LU2DPW, LU5FZ, CX9AU,

LU5FF, and PY3FF. CX1FK, LU2DEK, LU9DO, CX5CR, LU6DC, PY3OR and

LU9EHF were worked on SSB. On Sunday, May 5, the SFI was still over

135 and I worked CE2AWW weakly on CW, although I didn't seem to have

a good strong Es link like on Saturday. Still searching for HC, CP

and PZ."

TEP refers to Trans-Equatorial Propagation. Check the W7GJ website

at http://www.bigskyspaces.com/w7gj/. Lance invites us to use EME

(moonbounce) and check some of the references on his website.

Paul Harden, NA5N of Socorro, New Mexico wrote about a fascinating

project at the Very Large Array, the world's largest radiotelescope,

where he works:

"I am an electronics engineer at the Very Large Array (VLA) radio

telescope. My current project is our low-band system (60-500 MHz)

and the Long Wavelength Array (LWA) for 10-88 MHz. Though a few

years away, one of the science goals of LWA is to make real time 3D

maps of the ionosphere. The prototype system clearly paints the

locations of the E/F layers and it's depths as it migrates around.

Really cool, and when completed, should be made publicly available

on the web and a great tool for hams."

He sent this link to the project:

http://www.aoc.nrao.edu/~pharden/LBR/lbr.htm.

Jay Miller, N4NUI of Sandy, Utah wrote about what happened on

6-meters on May 2:

"During the afternoon of May 2 there was a great opening on

6-meters. It was obvious there were many paths open north and south

from the QSOs I could hear. I was mobile up in Antioch, Illinois

(EN52wk) and heard stations to the SE down to South Florida and SW

to West Texas. It was pouring rain and I couldn't get out of the

vehicle to tune the manual screwdriver without getting soaked to the

bone.

"I fixed that problem this afternoon (May 3) by driving up to

Milwaukee and buying a Little Tarheel II. I got it on the vehicle in

time to make a contact in the early evening with K5WLT and WP4O with

good signals as the opening started to close. Let's hope this is a

harbinger of things to come this summer.

"I travel for my job and I am sure glad I haul around a HF rig and a

Gorilla magnetic mount for the rental cars. A traveling ham using

rental cars has to ask for the same rental models each time once one

finds out how to get through specific firewalls to the battery."

Floyd Chowning, K5LA of El Paso, Texas wrote on May 4: "I had a nice

contact on 2-meter SSB this morning on 144.2 MHz at 1516 UTC with

WA7KYM in Cheyenne, Wyoming. Cheyenne is 639 miles from El Paso, TX

according to QRZ using grid squares. I am in DM61 and WA7KYM is in

DN71. This was my first contact with a Wyoming station."

Jon Jones, N0JK of Kansas wrote on May 4: "Interesting opening today

from the Midwest to South America.

"I was mobile (XYL driving) on K-10 just east of the K-7

intersection in Olathe and heard K3PA, K0HA and N0XA CQing or

calling some of the DX.

"No DX heard until 2150 UTC when PY3RO showed up on 50.115 MHz SSB.

He worked a local in Kansas City and I called after their Q. Had a

quick QSO with Raoul, he peaked to 5x7. During our QSO another KC

local came up on freq. and said my transmit audio was bad! (It was

due to voltage drop using a cigarette lighter plug to run the radio

in the car. I normally use jumper cables directly off the car

battery to run the radio). The next couple of times I went back to

PY3RO and listened, the local kept telling me 'OM your audio is

bad.' Guess he didn't hear the PY. First Brazil 6 meter QSO since

2001. I did not hear any other DX stations. My mobile set up is a 2

meter 5/8 wave whip and the FT-897."

Jeff Hartley, N8II of West Virginia wrote on May 7 about great

conditions back on April 7-11. He worked both Europe and Asia on 12

meters, and on April 9 on 10 meter CW running 5 watts he worked

9A4WY in Croatia who gave Jeff a signal repot of S9 plus 10 dB.

Jeff continued, "Throughout the last month, except during disturbed

conditions, 15 has been open to EU many hours, sometimes as late as

2200-2400 UTC and open about 90% of the days to Indonesia with good

signals from around 1300-1600Z. 20 meters is consistent every

morning with good VK signals from about 1115-1430 UTC or so and long

path southern Africans. On April 28, 15 meters was in good shape to

Russia in the UA1DZ contest logging Many stations in northern Europe

as well as UP0, UC0, and RN9. Many St. Petersburg area Russians were

active and it was fun working them as well as hearing them working

each other.

"On the April 29-30 with only 200 watts between 0200-0315 UTC, I had

a huge number of Russian stations call on 20 CW, some of the most

fun and biggest number of Russian callers in 40 years on the air. 43

stations were logged in an hour. Conditions were extremely good from

central Asia all the way east to DL on April 29, logging all Russian

call areas except for 0 as well as EX8AD and many Ukrainians. On

April 30, Asia was not quite as good, but many UA3 and UA6 area

stations called with the third QSO of the run being UA0YM in zone

23. Earlier around 2340-0030 UTC there was a large increase in EU

and Middle East activity on 17 meter CW logging UT3, A65BR, YO5,

SV1NN/3, and MU0FAL. On 20 CW I logged Z33Z. there was a real air of

excitement on both sides of the Atlantic over the great conditions."

ARLP018 Propagation de K7RA

Solar activity made a healthy jump over the past week, with average

daily sunspot numbers up over 30 points to 120.9, and average daily

solar flux increasing over 27 points to 136.5.

The most active day for geomagnetic indices was May 1, when the

planetary A index reached 21 and the high-latitude college A index

(measured near Fairbanks, Alaska) was a whopping 57. That number has

been higher, but only twice in the past six months, when it was 64

on March 1 and 79 on March 17.

The latest forecast has solar flux at 155 on May 3-4, 150 on May

5-6, 145 on May 7-9, then 140, 125 and 120 on May 10-12, 125 on May

13-15, 120 on May 16-17, then 125, 120, and 130 on May 18-20, 135 on

May 21-22 and 130 on May 23-24.

Predicted planetary A index is 8 on May 3-4, 12 on May 5, 8 on May

6, 5 on May 7-20, then 15, 10 and 15 on May 21-23, and then 5

forever after that. This is from a 45 day forecast, so we won't

really see quiet conditions forever, but the forecast ends on June

16 with planetary A index of 5 until then.

F.K. Janda, OK1HH has another short forecast for geomagnetic

conditions, like last week. He sees the geomagnetic field quiet to

unsettled May 3-10, quiet to active May 11-12, and quiet to

unsettled May 13-19. That's it!

NASA released a new solar cycle prediction on May 1, but it wasn't

really new. These arrive at the start of every month, and remain the

same since March 1. On March 1, 2013 the prediction for the smoothed

International Sunspot Number at the cycle peak shifted from 69 to 66

for Fall 2013. The 2013 Autumnal Equinox begins in about four months

and three weeks. This week the May 2013 issue of CQ Magazine

arrived, and across the top of the cover was this headline: "Another

Double-Peak Sunspot Cycle?" We certainly hope so.

Time to review our 3-month moving average of sunspot numbers, which

has increased. The average daily sunspot number for February, March

and April was 85.2. The average daily sunspot number for the three

month periods centered on September 2012 through March 2013 were

81.2, 82.3, 74.4, 82.8, 73.6, 80.7 and 85.2. This is a moving

average, so 81.2 was the average for August through October 2012,

82.3 was September through November 2012 and so on. But this

involves a bit of cherry picking of the data, as the three previous

period's averages were 96.5, 91.9 and 89.9.

The average sunspot number for the month of April was 112.8, for

March it was 81.1 and February was 60.1.

Eric Ferguson, VE3CR of Burlington, Ontario sent his father-in-law

Bruce Jones an article about solar flares, and they both wondered

why there are no solar flares at the Sun's poles.

I passed this question on to Robert Steenburgh, KA8JBY who is a

Senior Space Weather Forecaster at the NOAA Space Weather Prediction

Center.

Robert wrote, "Flares are thought to originate from the deformation

of magnetic field lines which break and reconnect. There is a

latitudinal band in which this magnetic flux emergence (and hence

sunspot formation) and deformation occurs.

"Sunspots typically form at mid-latitudes (equatorward of around 40

degrees) at the beginning of the solar cycle, and the breeding

grounds drift towards the equator over the course of the cycle. This

behavior is attributed to the solar dynamo. See

http://solarscience.msfc.nasa.gov/dynamo.shtml.

"A cartoon depiction of the dynamo process is here:

http://www.nasa.gov/images/content/144061main_CycleDiagramLG.jpg

"You can find a paper on flare distribution for Solar Cycle 23 here:

http://www.ias.ac.in/jaa/junsep2006/JAA10.pdf

"There were 4 flares identified poleward of 50 degrees latitude in

that paper, out of a total of 20,186.

"The poles are usually dominated by coronal holes and 'open'

magnetic field lines that extend out into the heliosphere. So the

mechanisms for flare formation are generally absent."

David Moore sent a link to a NASA video showing ten coronal mass

ejections over five days in April:

http://www.nasa.gov/multimedia/videogallery/index.html?media_id=162261751

Mike Snyder, KN8J who lives a few miles south of Harrisville, West

Virginia in EM99lf wrote this morning, May 3: "My wife and I are

early risers. I mean real early. We're up about 3AM. Generally

speaking, 3 to 5AM produces some fair DX for me.

"Lately it's been getting a bit better on the 20 and 30 meter bands.

The South Pacific is usually open at these hours. I've managed a

couple QRP contacts with Hawaii. I've noticed parts of Europe open

as well. I had a solid QSO with OK1HB from the Czech Republic on

14.062MHz. I was running 100 watts barefoot for this one.

"This morning I finally worked a new one: A35JP in Tonga on 14.003

MHz running up two at 0736 UTC.

"Well, gotta go...someone just spotted FO/KH0PR!"

Mike runs a Cushcraft A4 antenna on a 40 foot tower with the two

rear elements askew due to high winds last month. On 160 and 30

meters he uses a fan inverted vee dipole at 35 feet.

He sent this final note: "Just worked A35UD on 10.108 MHz at 1010

UTC. Too bad I gotta go to work now!"

121.9, 127, 131.7, 142.4, 154.4, and 159.2, with a mean of 136.5.

Estimated planetary A indices were 8, 17, 6, 5, 5, 7, and 21, with a

:( 

All,

I am sad to report to you that Jack Springer, K5JVS, has passed away. His obituary is in this morning's print edition of the Norman Transcript, but as of 8:45, is not yet available to read online.

Personally, Jack never failed to speak an encouraging word to me. SCARS has lost a great friend, mentor, and operator. A true gentleman.

Amateur Radio Enforcement: FCC Reduces Pennsylvania Ham's Fine

 

After affirming it was going to uphold a forfeiture in the amount of $4000 to Jose Torres, N3TX, of Philadelphia, Pennsylvania, the FCC decided to lower the fine to $3500. The FCC issued the fine in May 2011, saying that Torres' willful and repeated operation on an unauthorized frequency in April and June 2008 was in violation of Section 1.903(a) of the FCC's rules. Torres filed a Petition for Reconsideration in July 2011, asking that the FCC cancel or reduce the fine based on his inability to pay the full amount. Read more.

Support ARRL: ARRL Announces a Campaign for Its Second Century

 

As the ARRL draws closer to celebrating its Centennial in 2014, its Board of Directors has launched an unprecedented $10 million fundraising initiative to build the ARRL Endowment and strengthen the organization's financial future. Led by the ARRL Board and an eight-member Second Century Campaign Committee -- headed by David W. Brandenburg, K5RQ -- the campaign has already raised more than $4 million toward this goal. Plans are to reach that goal by the end of ARRL's centennial year in 2014.

"The vision of the ARRL Second Century Campaign is to secure significant financial resources that will open a path to passionate involvement in Amateur Radio for new generations," she said. "In this, it will provide opportunities for educational enrichment, community service and personal achievement through the exploration and use of the magic of radio communication." Read more.

Dayton Hamvention® Announces 2013 Award Winners

 

The Dayton Amateur Radio Association (DARA) -- host of the Dayton Hamvention® -- has announced the winners of its four annual awards for 2013: the Amateur of the Year, the Technical Excellence Award, the Special Achievement Award and the Amateur Radio Club of the Year. These recipients will be honored at Hamvention in May. Each year, DARA invites the amateur community to nominate hams who have made significant contributions to the Amateur Radio Service. Read more.

Check Out the April Issue of QST

The April issue of QST celebrates 75 years of W1AW, the Hiram Percy Maxim Memorial Station. So grab your print edition of QST -- or settle in with your computer or tablet to read the digital version -- and discover what the April issue has to offer.

Remote operation of your station via the Internet is gaining popularity. While operating the rig and antenna selector is fairly simple, controlling other station functions remotely can be a bit of a challenge. In his article "Remote Control of Accessories via the Internet," Jon Crisman, W0JEC, explains how to make this functions a bit simpler. In "The 2 Meter Q-Pole," Eric P. Nichols, KL7AJ, explains how this attractive and somewhat strange-looking antenna is the only kind of antenna capable of radiating omnidirectional diagonal polarization. In the first of a series of one night, easy to build projects, Paul Danzer, N1II, presents "Done In One: Temperature Alarm," which demonstrates how to build a device to warn you if your rig is overheating.

 

The world's most famous Amateur Radio station -- W1AW -- turns 75 in September. W1AW Station Manager Joe Carcia, NJ1Q, takes readers on a photo tour of the ARRL's flagship station in "75 Years of W1AW." In his article "Field Day the Solo Way," Thomas Mills, NU9R, gets a jump on Amateur Radio's most popular on-the-air event by showing that roughing it on Field Day can teach some valuable lessons. ARRL News Editor S. Khrystyne Keane, K1SFA, reports on the ARRL's Board of Directors Annual Meeting and presents the recipients of three of the ARRL's annual awards in "ARRL Board of Directors Convenes in New Orleans for 2013 Annual Meeting."

ARRL Membership and Volunteer Programs Assistant Manager Norm Fusaro, W3IZ, takes a look at the Yaesu FTdx3000 HF and 6 meter transceiver in this month's Product Review. He says this rig "brings a boost in features and performance to Yaesu's mid-priced transceiver range." You can find a video overview of the Yaesu FTdx3000 in the digital edition of the April issue of QST.

Of course, there are the usual columns you know and have come to expect in the April issue of QST: Happenings, Hints & Kinks, Eclectic Technology, The Doctor is In, Short Takes, Vintage Radio, How's DX? and more. Look for your April issue in your mailbox and in your inbox. QST is the official journal of the ARRL, the national association for Amateur Radio.

ARRL UHF/Microwave Band Plan Committee Seeks Comments on Draft 5 and 10 GHz National Band Plans

 

Last year, the ARRL UHF/Microwave Band Plan Committee prepared -- and the ARRL Board of Directors approved -- updated national band plans for the amateur bands between 902 MHz and 3.5 GHz after receiving extensive and helpful input from the user community. Last year, after the ARRL Executive Committee extended the Committee's charter to include the 5 and 10 GHz bands, it solicited additional input concerning usage on those two bands. The Committee has prepared draft band plans for 5 centimeters (5.650-5.925 GHz) and 3 centimeters (10-10.500 GHz). Read more.

Solar Update

The Sun, as seen on Thursday, March 21, 2013 from NASA's SOHO Extreme Ultraviolet Imaging Telescope. This MDI (Michelson Doppler Imager) image was taken in the continuum near the Ni I 6768 Angstrom line. The most prominent features are the sunspots. This is very much how the Sun looks in the visible range of the spectrum.

 

Tad Cook, K7RA, reports: This past week, the average daily sunspot numbers were up 16.2 points to 101.1, while the average daily solar flux remained about the same, rising from 118.5 to 119. An eruption on March 15 caused a coronal mass ejection (CME) that hit Earth on March 17, causing the planetary A index to jump to 46. The predicted solar flux is 105 on March 21-22, 100 on March 23-27, 95 on March 28, 100 on March 29-30, 105 on March 31, 110 and 120 on April 1-2, 125 on April 3-6, and back down to 120 on April 7-8. The planetary A index is predicted to be 10 and 8 on March 21-22, 5 on March 23-27, 18 and 10 on March 28-29, and back down to 5 on March 30-April 16. Look for more on the ARRL website on Friday, March 22. For more information concerning radio propagation, visit the ARRL Technical Information Service Propagation page.
