Good morning. It's Sunday the 9th of October and here is the GB2RS news broadcast, prepared by the RSGB and intended for all radio amateurs and short-wave listeners. Next weekend sees the 37th Jamboree on the Air and this year, over 250 Special Event callsigns have been issued. The event lasts from 0001 UTC on Saturday the 15th to 2359 UTC on Sunday the 16th and Scouts and Guides all over the world will be using amateur radio to celebrate their shared interest. All UK groups which have told RSGB HQ that they are participating, have been sent an information pack which includes a list of stations taking part. Anyone else who would like a copy of this list is asked to send an A5-size Self-Addressed Stamped Envelope to the Amateur Radio Department at RSGB, Lambda House, Cranborne Road, Potters Bar, Herts EN6 3JE. A meeting between the RSGB and the Director of the Science Museum was scheduled for last Thursday to discuss the future of the GB2SM amateur radio exhibit. More information on this next week.

The attractions include technical talks, calibration and alignment facilities, plus of course the usual round table discussions. There will be a bring and buy stand, hot drinks and snacks.

It is with regret that the Radio Society of Great Britain announces the resignation from Council on 10 September 1994 of Immediate Past President Peter Chadwick, G3RZP. Peter's resignation follows a decision by a majority of Council to propose certain minor changes in the Articles of Association to the membership of the Society at an Extraordinary General Meeting to be held in December 1994. The full proposals and explanatory commentary will appear in the Society's Annual Report and Accounts to be circulated to members during November. If accepted, the changes allow Council a degree of flexibility in the future conduct of its business and correct certain anomalies that exist in the current wording of some Articles. Peter felt that he could not support the changes at this time and, because Council is collectively responsible for sponsoring these amendments to the Society's constitution, decided he should resign his seat on Council. Council will miss Peter's considerable technical expertise and good-humoured contributions to its work and wishes him well in the future. The Port Talbot Amateur Radio Society celebrates its 50th Anniversary in 1996 and is calling all ex-members of the Neath-Briton Ferry (now called the Port Talbot) Amateur Radio Society formed in 1946.

And now the solar factual data: The period from the 26th of September to the 2nd of October has seen solar activity at very low levels, with geomagnetic activity declining to quiet conditions. No flares were reported. Sunspot indices generally declined throughout the period and meaned at 28. Solar flux levels have varied little day to day and averaged only 74 flux units. The geomagnetic field generally declined from unsettled levels of up to 20 units on the 26th of September, down to very quiet levels of only 3 units by the 1st of October. The period averaged an Ap of 10.7 units. The state has been 'nil, nothing to report'. The 90 day flux level was 78 units on the 30th of September. The aa indices, as reported by the British Geological Survey for the period from the 20th to the 26th of September, were mainly quiet. The 23rd was down to only 7.3 nanoTeslas with the most disturbed day being the 25th, up to 29.0 nanoTeslas with periods up to 80 nanoTeslas. The period averaged 15.5 nanoTeslas, about K2. The X-Ray flux levels have remained very low only, averaging A2.3 units. The electron fluence varied little and stayed at moderate levels. The September sunspots averaged RI 26.7, with a high of 65 on the 5th, and lows of only 8 on the 15th and 16th. The six month smoothed number for March was 34.4 plus or minus 0 5. The solar flux average for September was 81.1 units, with the high at 95 units on the 5th, and the lows at 70 units on the 17th, 19th, 20th and 21st. The geomagnetic field averaged an Ap of 10.1 units with the most disturbed day being the 9th up to 30 units, and the quietest being the 22nd and 23rd with levels down to only 3 units. I'll repeat the figures. Spots - 28; Flux - 74; Ap index - 10.7; X-ray flux - A2.3. Averages for September: Spots RI 26.7; Flux 81.1; Ap index 10.1. Now the ionospheric data for Central France: The F2 daytime critical frequencies at Poitiers averaged 6.9MHz, with the best day being the 1st of October, up to 7.5MHz. The darkness hour lows averaged 2.9MHz with spread F being reported on some days, lasting up to 6 hours on the 28th. Very small amounts of blanketing E was also reported. With the seasonal changes the highs are now becoming earlier about 18.00 hours, with the early morning lows at 05.00 hours. I'll repeat the figures. Highs - 6.9MHz; lows - 2.9MHz. And lastly the solar forecast: This week the more active side of the sun will be rotating away; solar flux figures are expected to be into the high 70s but falling throughout the period. The geomagnetic field is expected to be mainly quiet. MUFs in the south are expected to be about 21MHz during daylight, with darkness hour lows being about 10MHz. North/south paths are expected to be best, but east/west paths are expected to be open during darkness hours on the lower HF bands. And that's the end of the solar information. Finally in the main news, SSL has informed the Society that as of last Wednesday morning, the latest callsigns allocated were in the G0 Victor Hotel and G7 Tango Tango series, and Novice calls in the 2 0 Alpha India and 2 1 Delta Kilo series. -- NEWS FOR THE SOUTH EAST First an announcement concerning taking the RAE examination at Hatfield: The University of Hertfordshire Amateur Radio Society has arranged for the City and Guilds RAE examination to be held at the University's Hatfield campus on Monday the 5th of December.
