A NASA funded sounding rocket mission will launch from an atoll in
the Pacific in the next few weeks to help scientists better
understand and predict the electrical storms in Earth's upper
atmosphere. These severe weather outbursts can interfere with
satellite communication, the global positioning system and other
space-based communications including some used by radio amateurs. The
EVEX mission will consist of the launch two rockets from the Marshall
Islands for a twelve minute information gathering journey through the
equatorial ionosphere above the South Pacific. The twin spacecraft
will measure events in two separate regions of the ionosphere to see
how they work together to drive the ionosphere from placid and smooth
to violently disturbed. The launch window for EVEX runs until 10 May.
More on this propagation study mission is online at
tinyurl.com/nasa-storm-rocket.
The Radio Communications Foundation will be holding a Trustees
meeting on 15 May. The objectives of the charity are "to advance the
education of the public in the science and practice of radio
communication and electrical engineering and to promote the wider
benefits to the public resulting from such education and training".
The Trustees welcome requests for funding for projects that are in
line with these objectives. At its May meeting the Trustees will be
looking specifically at smaller projects. If you have a project that
you think would benefit from RCF funding and would qualify, then
please send details of it to marilyn.slade<at>rsgb.org.uk or by post
to The Secretary, Radio Communications Foundation at RSGB HQ. If you
are proposing or considering undertaking a major project requiring
funding then please let the Secretary know so it may be considered at
a later date. All decisions on whether to provide financial support
are made by the Trustees and there is no certainty that any project
proposed will receive funding.
Due to the demand for tickets, the RSGB Centenary dinner booking

Now the solar report for the period from Friday 26 April to Thursday
the 2nd of May, compiled by Martin Harrison, G3USF, on Friday 3rd May.
Solar activity was mostly low, though numerous C-class flares were
reported every day. The level rose to moderate on the 2nd, when an
M1.9 flare was reported. The solar flux increased from 122 on the
26th to 165 on the 30th, the highest level since January. The average
over the week was 144, which is 33 higher than the previous week. The
90-day average gained 3 points to 115. The X-ray flux was also up,
from an average B4.5 units to B7.9. Geomagnetic activity was
variable. A C7 flare on the 24th resulted in a short, sharp
disturbance early on the 26th and an Ap index for the day of 18
units. HF MUFs were depressed by a couple of MHz for most of the day.
During the next few days geomagnetic activity was low, with the Ap
index in single figures. There was another disturbance on May 1st. A
high-speed coronal stream caused a minor storm when the
interplanetary magnetic field turned south to -11 nanoTeslas.
Particle densities, which were generally low, surged to 43 per cubic
centimetre. The Ap index for the day was 21. VHF aurora was reported
from midday through to the evening. As usual, its main UK
beneficiaries were in Scotland. However, just before that
disturbance, the whole UK had strong Sporadic-E at both 50 and 70MHz,
and the MUF was reported to have reached 87MHz.
Now the forecast. Solar activity is likely to remain mostly low.
However, several sunspot groups now on the solar disc or about to
turn into view have the potential for M-class flares. The solar flux
may fall back from the level of recent days, possibly into the 130s.
The geomagnetic field is expected to be mostly quiet, though a
recurring coronal hole may lead to slightly higher levels at the
start of the week. The major uncertainty is whether one of the
sunspot regions facing us will produce a coronal mass ejection,
bringing a disturbance later in the week. MUFs at equal latitudes
will be around 23MHz in the south and 20MHz in the north. Darkness
lows will again be about 12MHz. Sporadic-E up to 70MHz should occur
on most days. It is still a little early in the season for openings
on 144MHz, but they have been known. So it's a good idea to keep an
ear on Band 2 FM for rising MUFs. Paths to South America this week
should have a maximum usable frequency, with a 50 per cent chance of
a contact of 28MHz. The optimum working frequency, where there should
be a 90 per cent prospect of success, will be 22MHz. The best times
will be between 1300 and 2100UTC.
And that's all for this week from the propagation team.
And that's the end of the main news for this week prepared by the
Radio Society of Great Britain. Items for inclusion in subsequent
bulletins can be emailed to gb2rs<at>rsgb.org.uk to arrive by
10:00 on the Thursday before transmission.
