The news headlines:
Olympic Flagship station working via satellites
RSGB statement criticises PLT growth
Consultation now running on RSGB Interim Board Strategy and Governance proposals
Olympic Special Event Station 2 Oscar 12 Whiskey has been active on the amateur radio satellites, working stations in the USA and across Europe. The 2o12W satellite station has been operated by Ken, GW1FKY. He is using a Kenwood TS-2000 feeding a 5 element dual-band Elk antenna mounted on a rotator on the portable cabin. Other Olympic stations have also been enjoying great success on the bands and getting interesting visits from the public. For details of all the Olympic stations, check out the RSGB website at www.rsgb.org/operating/ and click on London Olympics 2012.
The RSGB has issued a statement expressing grave concern at the continuing headlong rush to legitimise high levels of emission from PLT devices, in contravention of the Essential Requirements of the EMC Directive. You can read the full statement on the RSGB website www.rsgb.org, click on Update on draft PLT standard prEN50561-1.
Consultations are now running on the RSGB Interim Board proposals on Strategy and Governance. All members are encouraged to share their views, on what are arguably the most important consultations that the Society has ever undertaken. All responses will be carefully considered and the more input that is received, the more robust the final documents will be. The Interim Board intends to bring final proposals for Governance to an Extraordinary General Meeting in November and needs your comments by 20 August. Two Litmus Tests are being run through the RSGB website to facilitate comment and discussion on the proposals. Alternatively you can send comments by e-mail to firstname.lastname@example.org or email@example.com, or submit written comments to the Board at HQ. Follow the link from the main page of the RSGB website, www.rsgb.org.

And now the solar factual data for the period from Friday the 27th to Thursday the 2nd of August, compiled by Martin Harrison, G3USF, on Friday the 3rd of August
Solar activity ranged between very low and moderate. Every day brought a crop of C-class flares, but they had little apparent impact on propagation. M-class flares were reported on the 27th, 28th, 29th and 30th. Of these, an M6.1 flare on the28th was the most significant, bringing increased geomagnetic activity on the 2nd. Solar flux levels increased from 123 on the 27th to 150 on the 1st, then 135 on the 2nd. The average was 135 units – 36 up on the previous week. The 90 day solar flux average on the 2nd was 127, two units up on last week. X-ray flux levels increased from B4.8 on the 27th to B6.3 units by the 1st, averaging B5.5. Geomagnetic activity was at quiet to unsettled levels for much of the period, However, on the 30th, the coronal mass ejection associated with the flare on the 28th brought ‘active’ levels and an Ap index of 13. A brief disturbance occurred on the 2nd, when the Ap index was up to 16. For most of the rest of the week it was in single figures. The average Ap for the week was 9. Solar wind speeds reported by the ACE spacecraft ranged between 307 and 455 kilometres per second. Particle densities were generally low, but reached 14 per cubic centimetre during the disturbance on the 2nd. Bz varied between minus 11 and plus 13 nanoTeslas during that disturbance, but otherwise ranged between minus 3 and plus 4 nanoTeslas. Although the disturbance on the 30th was quite mild one, it brought extensive auroral propagation from early afternoon to mid-evening, which at peak reached southward to central England. Though the event on the 2nd was more intense few auroral contacts were reported.
And finally the forecast. Solar activity and solar flux levels are expected to be below last week’s levels, though there is a chance of occasional M-class flares bringing moderate levels. The solar flux should be in the 130’s for most of the week. The geomagnetic field is expected to be ‘active’ at times during the next few days due to a recurring coronal hole. Quiet conditions should return by midweek, although an Earth- directed coronal mass ejection cannot be totally ruled out. MUFs at equal latitudes should be around 21MHz in the south and 18MHz in the north. Paths to Japan, currently among the more difficult, should have a maximum usable frequency, with a 50 per cent success rate, of around 22MHz. The optimum working frequency with a 90 per cent success rate will be about 16MHz. The best time to try this path will be between 1000 and 1400 hours.
The summer sporadic-E season is now well past its peak, but brief openings may still occur on both 50 and 70MHz. MS operators should find the Perseids shower moving towards its peak next weekend.
And that’s all for this week from the propagation team.
