GB2RS AMATEUR RADIO NEWS BROADCAST
----------------------------------
This information is prepared by the Radio Society of Great
Britain and broadcast each Sunday on the 80, 40 and 2 metre bands by
stations in all parts of the country.
This is the GB2RS news broadcast for the week commencing
Sunday, 25th August.
SOLAR FACTUAL DATA
------------------
We begin this week with the solar factual data for the period
between the 11th and the 17th of August. There was a decline in
solar flux levels during this period and a level of only 66 units
was recorded on the 13th. This is amongst the lowest level recorded
during the current cycle. The average for the period was 67 units.
The geomagnetic A index has continued to decline from its recently
active state and it was down to quiet levels by the end of the
period. The average was 8 units, although a level of only 5 units
was recorded on the 16th.
The sunspot count has returned to zero for most days and there
is only one potential spotted region currently present on the sun.
The solar wind particle input has been very low. The Inda index for
the period between the 4th and the 10th of August was quiet.
IONOSPHERIC DATA FOR ENGLAND & WALES
------------------------------------
The F2 critical frequency daily highs at Appleton averaged 6
MHz over the period. However, the figures varied between 6.7 MHz on
the 12th and 5.3 MHz on the 15th. These variations appear to be on a
random basis, with no discernible pattern. The darkness hour lows
averaged 2.8 MHz and held up well, although seasonal changes are now
expected to force these levels down. Spread F was reported,
particularly on the 12th and 13th, which did not help. Sporadic E
was reported on most days and lasted for up to 5 hours on the 15th.
IONOSPHERIC DATA FOR SCOTLAND AND N. IRELAND
--------------------------------------------
The F2 critical frequency daily highs at South Uist averaged
5.2 MHz. Day-to-day variations between 4.7 MHz on the 10th and 5.7
MHz on the 17th were recorded. Sporadic E was reported at odd times,
particularly between the 10th and the 14th. It lasted for 4 hours on
the 11th. The darkness hour lows averaged 2.2 MHz but spread F was
reported on most days. The present levels could well be affected by
the seasonal changes which are slowly taking place and also by
geomagnetic changes which tend to have more effect in the north.
SOLAR FORECAST
--------------
The only potentially spotted region at present on the sun will
rotate into view this week. However, not much is expected of it.
Solar activity is expected to remain very low. The Solar Maximum
Mission satellite has recorded coronal mass ejections, which are
partly due to the remnants of filament disappearance. This will
probably maintain geomagnetic activity at up to unsettled levels,
sub-storms may be reached on the 28th or 29th. Ionospheric levels
are expected to deteriorate as the week continues and northern
stations especially could be affected by the expected increase in
magnetic activity. F2 critical frequency levels will probably be at
their lowest for the present rotation, levels may only reach around
4.5 MHz in the north and 5.5 MHz in the south.
And now the rest of the news - as a matter of fact there isn't
a great deal this week, probably because many radio amateurs are out
of their shacks and soaking up the sunshine by the seaside.
For some months the Society has been considering its position
with regard to the new strategy being operated by the Radio
Investigation Service of the Department of Trade and Industry. This
topic was reported in detail in the April 1986 edition of the RSGB
Bulletin and since then the Society has been considering what action
it should take. The September edition of the Bulletin, which will be
sent to members in a week or so, carries an outline of the Society's
initial intentions with regard to EMC problems which can arise
between radio amateurs and neighbours. Members are asked to look out
for this item and read it carefully.
The Telford Mobile Rally takes place next Sunday, the 31st of
August. The venue this year is the Telford Racquet and Fitness
Centre, which is close to the old venue of Telford Town Centre. As
well as numerous trade stands there will be a giant flea market; a
town park next to the centre has attractions for all the family,
including children. There is also an ice rink next to the centre,
which will suit the energetic. Talk-in will be available via GB4TRG
on S22 and SU8 and catering and bar facilities will be available on
the site. More information is available from Martyn, G3UKV, on
Telford 55416. The STD code is 0952.
Special event stations to listen for this week include:-
GB2NWR - until the 25th of August - Bank Holiday Monday, at the
Harewood Steam Rally.
GB2RGD - on the 30th of August at Clydale Training Centre at
Woodford Bridge. The station will be active from 9am until 6pm clock
time on HF, VHF and possibly 70 cms celebrate the public open day
at the Dog Training Centre.
GB2GWR - today at the steam-up day of the Gwili Railway at Bronwydd
Arms Station, near Carmarthen, Swansea Amateur Radio Society will
operate mainly on HF, but VHF will be used as much as the location
allows.
GB6SLS - until the 30th of August at Walesby Forest Scout Camp near
Newark, Nottinghamshire. This is the camp of the 88th Leicester
Scout Group. Due to the camp's strict schedule, operating times
might be difficult to schedule, but it is expected to be active
during the late evenings. Operation will be on 2 metres, both on SSB
and FM
GB6APS - at the Abbey Park Show in Leicester on the 25th and 26th
of August. There will be special QSL cards available and the station
is open to visitors.
GB4NCR - until the 26th of August at the Northern Centres Caravan
Rally at Bedale in North Yorkshire. The station is run by members
