The second WSPR beacon in Africa, 5X7JD, has gone into service. The
beacon is hosted by Jack, 5X7JD who is located in Masaka, Uganda. The
system has 1W output and cycles through 80, 40, 30, 20, 17, 15, 12 and
10m, so you can hear the WSPR signal returning every 16 minutes. The
antenna is a HyGain Av 18VS multi-band vertical. The beacon hardware is
an embedded system based on a PIC 18F2455 MCU, an Analog AD9851 DDS chip
and a MOSFET PA with selectable filters. Time and location information
are derived from an attached GPS receiver. You can read more about the
station at www.hamradiosafari.com.

Now the solar factual data for the period from the 29thd of March to the
4th of April, compiled by Neil Clarke, G0CAS on the 5th of April.
The solar disc had spots visible every day. Up until the end of March
there as only been six spotless days, comparing that for the same period
last year there was 76. Solar activity remained at very low levels.
However, a long duration B7 solar flare occurred on the 3rd and produced
a coronal mass ejection that appeared to be Earth directed. Solar flux
levels declined slightly from 83 units on the 29th to 76 by the 2nd. The
average was 80 units.
The 90 day solar flux average on the 4th was the same level as last week
at 83 units. X-ray flux units varied little day to day and averaged
A3.5.
Geomagnetic activity started at quiet levels but on the 1st, 2nd and the
4th increased to slightly unsettled. The Ap index on the 4th was 13
units. The average was Ap 8 units. Solar wind data from the ACE
spacecraft saw solar wind speeds increase from 350 kilometres per second
to 560 by the 3rd. Particle densities were mostly low but increased
briefly to around 20 particles per cubic centimetre on the 29th to the
31st. Bz varied no more than plus and minus 8 nanoTeslas during the
period.
Now the latest news on the Solar Dynamics Observatory. During the past
week all nine doors were open and the CCDs are cold. For the next
several weeks SDO scientists and engineers will work to check out and
calibrate the instruments and to coordinate the spacecraft and
instruments. SDO needs to point at the Sun very accurately while taking
an image every 3/4 of a second, which means rotating shutters and
filters, rotating the high-gain antennas to keep them pointed towards
New Mexico, and rotating the entire observatory once per orbit to keep
it pointed at the Sun. Initial results will be released world-wide in
mid-April.
And finally the solar forecast. This week solar activity is expected to
be at very low to low. If the present state of the Sun continues then
spots are expected to be visible most days. Solar flux levels should be
in the 80's for most of the week. Geomagnetic activity should be quiet
everyday. MUFs during daylight hours at equal latitudes are expected to
be about 23MHz for the south and 20MHz for the north. Darkness hour lows
should be around 10MHz. Paths this week to the east coast of North
America should have a maximum usable frequency with a 50 per cent
success rate of about 20MHz. The optimum working frequency with a 90 per
cent success rate will be around 16MHz. The best time to try this path
will be between 1500 and 2000 hours.
And that's all for this week from the propagation team.
