Raynet Groups on Standby after London
Several Raynet groups in south-east England were put on standby
by their emergency planning units, following the terrorist bomb blasts in
London on Thursday 7 July. Groups in Buckinghamshire, Berkshire and East
Sussex were alerted during the morning and stood down in the late
afternoon. Mobile phone coverage was badly affected and many groups
operated listening watches on designated frequencies and local repeaters.
Other groups were kept informed of developments via e-mails from
Government Offices in their respective regions.The Southgate Amateur Radio Club has created a page on its
website where messages of sympathy may be uploaded.

The solar factual data for the period from 4 to 10 July , prepared by
Solar activity was moderate with M-class solar flares taking place on
the 7th and the 9th, the remaining day’s activity being low with a number
of C-class flares taking place. The largest solar flare was an M4 on the
7th. An earthward coronal mass ejection accompanied this flare and a
short-wave fadeout that lasted 43 minutes. Solar flux levels dropped from
127 units on the 5th to 102 by the 10th, averaging 117 units. The 90-day
solar flux average on the 10th was 97, three units greater than last week.
X-ray flux levels reduced slightly from B3 units to B1.9 by the 10th, with
an average of B2.6 units. Geomagnetic activity started at quiet levels
with the Ap index in single figures. Late on the 9th, due to the effects
of the coronal mass ejection from the 7th and a small coronal hole,
activity increased to sub-storm levels with an Ap index of 47 units. The
average was Ap 14 units. The ACE spacecraft showed solar wind speeds
dropping from 500 kilometres per second to 300 by the 9th. Speeds returned
to 500 kilometres per second on the 10th. Particle densities were low but
increased to 22 per cubic centimetre during the magnetic storm of the
10th. Bz varied between minus and plus 4 nanoTeslas on the quiet days and
between minus 22 and plus 19 nanoTeslas on the 10th.
HF propagation was similar to recent weeks, better for those who get up
early or go to bed late. 28MHz and 50MHz saw some good openings most days.
Also on 28MHz, the New York beacon, 4U1UN, which belongs to the world-wide
beacon network was heard in Germany. 50MHz was reported to be still open
at 0100UTC a few mornings ago. An aurora was reported during the afternoon
of the 10th.And finally the solar forecast. This week should see the
quiet side of the Sun facing us. Solar activity is expected to be very low
to low. Solar flux levels for most of the week should be in the 80s.
Geomagnetic activity should start at quiet levels but by midweek, due to a
recurring coronal hole, activity should increase. Quiet conditions should
return during next weekend. MUFs during daylight hours at equal latitudes
are expected to be around 19MHz for the south and 16MHz for the north.
Darkness-hour lows should be around 10MHz. Paths this week to India should
have a maximum usable frequency of about 23MHz, with a 50% success rate.
The optimum working frequency should be around 18MHz, with a 90% success
rate. The best time to try this path should be between 0800 and 1600UTC.
This week should still see sporadic-E openings taking place.

update, posted every Saturday evening and for more on propagation
generally, see http://www.rsgb.org/society/psc.htm.
