[DX-NEWS] ARLP031 Propagation de K7RA
SB PROP @ ARL $ARLP031 ARLP031 Propagation de K7RA ZCZC AP31 QST de W1AW Propagation Forecast Bulletin 31 ARLP031 From Tad Cook, K7RA Seattle, WA August 5, 2011 To all radio amateurs SB PROP ARL ARLP031 ARLP031 Propagation de K7RA Solar activity increased markedly this week, with the sunspot number rising to 130 on Monday, August 1, the highest since a reading of 131 on April 14, 2011. Average daily sunspot number more than doubled this week compared to last, rising nearly 54 points to 99.3. On Thursday I received a Significant Event Report from Rob Steenburgh, KA8JBY, Space Weather Forecaster at NOAA Space Weather Prediction Center: A trio of significant active regions produced a series of radio blackout (solar flare) events in the past few days. To date, three radio blackouts reaching the R2 (Moderate) level have been observed. Earth-directed coronal mass ejections have been associated with each of the biggest radio blackout events on August 2-4. Solar radiation enhancements have also occurred in conjunction with each of these events, with the solar radiation storm event threshold being exceeded to reach the S1 (Minor) level in conjunction with the August 4 event. Three coronal mass ejections (CMEs) are currently en route to Earth, with the commencement of geomagnetic storming expected early to mid-day on August 5 with the arrival of the CMEs associated with the August 2-3 events. The third of the string, seemingly the fastest CME, may catch up with the first two in the next 12-18 hours, compressing the plasma and enhancing the embedded magnetic field. Storming levels are expected to attain G3 (Strong) conditions. The current Solar Radiation Storm may experience a kick with the shocks, and attain S2 (Moderate) thresholds. Some level of geomagnetic disturbance is expected to continue through August 7 as the series of CMEs affect the Earth. Continued activity is likely from these regions as they continue to rotate off the visible solar disk over the next 7 days. The Space Weather Prediction Center will continue to monitor this event as it unfolds. Thanks, Rob! A NASA video shows a couple of the CMEs. Check http://www.nasa.gov/mission_pages/sunearth/news/News080411-dblpunch.html. The latest forecast on Thursday night has planetary A index for August 5-9 at 50, 30, 20, 15, and 10, then 8 on August 10-12, then 5, 8, 10, 15, 12, 10 and 8 on August 13-19. Solar flux predicted for August 5 is 115, 110 on August 6-7, 100 and 95 on August 8-9, then 85 on August 10-12, then 100 on August 13-16. The planetary A index at 50 is quite high. Geophysical Institute Prague predicts active conditions on August 5-7, unsettled to active August 8, quiet to unsettled August 9, and quiet conditions August 10-11. July is over, so let's look at some of the numbers. The average daily sunspot number for the month of July was 67.2, up from 55.5 for June. The moving three month average of daily sunspot numbers for May through July, centered on June was 61.5. The 3-month moving average centered on January through June was 35.3, 55.7, 72.3, 74.4, 65.9 and 61.5. Vince Varnas, W7FA of Portland, Oregon wrote on July 30: For the last week the ST0R DXpedition to South Sudan has had very weak signal strength here in the Portland area, particularly at night on the 17 meter band (18 MHz). Generally they are S-3, at best. At 0209 UTC on July 30 there was a M9 solar flare from a big sunspot. At 0522 UTC I heard and worked the ST0R station on CW with much, much louder signal strength, both directions. (They were at the noise or slightly above a few hours earlier. When I worked them on SSB on July 26 at 2303 UTC they were about S-4.) They were S-8 to 9 on the S-meter. The difference in signal strength between 'normal' and last night was about 30 db. Since it is a scientific fact that solar flares can and do enhance the reflectivity of the F layer, my conclusion is that this is what produced the markedly stronger signals from ST0R. Thanks, Vince. Sergej Ignatov, UZ2HZ of Kremenchug, Ukraine asked about a link to the Penticton source for thrice-daily solar flux readings, as the link he was using no longer works. Yes, they changed servers again, so the URL has changed. Try ftp://ftp.geolab.nrcan.gc.ca/data/solar_flux/daily_flux_values/fluxtable.txt in your web browser. The column you want is third from the right, the observed flux values, and the local noon (2000z) readings. Although readings are taken three times per day, the noon reading is the official solar flux for the day, also shown at http://www.swpc.noaa.gov/ftpdir/indices/DSD.txt in whole number resolution. As geomagnetic conditions change over the next few days, you can check http://www.swpc.noaa.gov/ftpdir/indices/DGD.txt for the planetary K index, updated every three hours. You can also check out http://www.swpc.noaa.gov/ftpmenu/forecasts/45DF.html every day after 2100z for an updated daily forecast of solar flux and

Here is the latest information regarding the South Sudan DXpedition from Paul, N6PSE: Dispatch Juba: Today, the Undersecretary of the Ministry of Communications and his staff visited the ST0R team and observed our operations. The Undersecretary has been very supportive of our plans to conduct this DXpedition to the new country of the Republic of South Sudan. Following the visit to the radio shack, we enjoyed a cordial lunch and exchanged documents to commemorate the first DXpedition to the Republic of South Sudan. The ST0R team is also assisting the Ministry of Communications with the ITU application for their own prefix. We are also providing them guidence to establish their own Amateur Radio activities.
