Hello all,
Due to continuing problems at GB7IPF/GB7CIP gateway, Andy/G4TNU has asked me
to
kindly forward his news bulletins from my BBS.
So here is the....
GB2RS Main News for Sunday 27th April 2014
The news headlines:
* KickSat deployed – stand by for Sprites
* TX-Factor to podcast GB2RS
* 3100 miles on 472kHz for ZL1BPU
The Kickstarter-funded KickSat satellite is safely in orbit after its
deployment on 17 April. Operating at an altitude of around 335km, an
internal timer is currently counting down to release the dozens of
Sprite micro-satellites that form its payload. This is due to occur
around 2000 GMT on Sunday 4 May. KickSat transmits 1W of telemetry on
437.505MHz, whilst the large-postage-stamp-size Sprites will send
10mW on 437.240MHz and use digital codes to identify themselves.
The popular new video streaming show TX-Factor is to begin podcasting
GB2RS News on a weekly basis, starting with this edition. TX News is
a new service that allows users to stream the news file or have it
emailed automatically every week. Full information can be found at
www.txfactor.co.uk
472kHz signals from Murray Greenman, ZL1BPU have been heard at a
range of over 3100 miles. Dereck Zeck, VK6DZ logged the transmissions
in Elleker, western Australia. Activity on 630m is quite common
between New Zealand and Australia, although generally over shorter
paths.
A new 9-day International Air-ambulance Weekend event, IAW, has been
announced by the new Amateur Radio Events Organisation. The inaugural
event will commence on 27 September 2014 and is in support of the
many air ambulance services around the world, particularly in the UK,
that are funded by donations. More details on the event, it aims, and
a form for free registration can be found at
www.radio-amateur-events.org
At 0032 GMT on 25 April an X1.3-class solar flare occurred, causing
an HF blackout on the Sun-facing side of the Earth. Reports say that
a coronal mass ejection was also produced but is not heading towards
Earth, so there is no chance of a corresponding geomagnetic storm.
Bletchley Park has been undergoing major restoration work funded by
the National Lottery, and the upgraded facilities will be open from
12 May. Admission to the RSGB National Radio Centre at Bletchley Park
has always been free to all but from 12 May RSGB Members will be able
to download a voucher from the RSGB website that permits free entry
to all the Bletchley Park Trust facilities.
A Multi-DF direction-finding competition is being held at Blake's
Wood in Danbury this afternoon, Sunday 27 April. Whether you are an
absolute beginner or an expert, this is the event for you. There will
be ten transmitters to find, ranging from easy to seriously hard.
Equipment and tuition are available. The event starts at 1pm and the
last transmission is at 4pm. After the event participants will be
heading to The Bell public house, 128 Main Road, Danbury CM3 4DT.
The ARRL Centennial station W1AW has been very busy since it first
hit the airwaves, often running solid pileups. At present W1AW/1 is
on the air from New Hampshire and W1AW/2 from New Jersey. Starting at
0000 on April 30, operation will shift to W1AW/1 in Connecticut and
W1AW/7 in Nevada. These will be active until 2359z on May 6. More

Now the solar factual data for the period from Friday the 18th to
Thursday the 24th of April, compiled by Neil Clarke on Friday the
25th of April.
Several large and magnetically complex sunspot regions were visible
during the period but only one M class solar flare took place and
that was a M7 on the 18th, however, numerous C class solar flares
took place every day. Only one new sunspot region appeared during the
week. Solar flux levels declined from 172 units on the 18th to 130 by
the 24th. The average was 153 units. The 90 day solar flux average on
the 24th was 156, that's one unit up on last week. X-ray flux levels
varied little day to day and averaged B7.6 units. Geomagnetic
activity started at quiet levels but during the 19th a coronal mass
ejection arrived that departed the Sun several days earlier. The Ap
index for the 20th and the 21st was 21 and 22 units respectively.
Quiet conditions returned from the 22nd. The average was 12 units.
Solar wind data from the ACE spacecraft saw solar wind speeds
increase from 360 kilometres per second on the 18th to 760 by the
20th. Speeds then gradually declined to 380 kilometres per second by
the 24th. Particle densities were moderate at around 18 particles per
cubic centimetre for the first four days but then declined to below
10 particles per cubic centimetre for the rest of the period. Bz
varied between minus 8 and plus 21 nanoTeslas on the most disturbed
day and between minus 2 and plus 5 nanoTeslas on the quietest day.
Finally, the solar forecast for the coming week. This week the quiet
side of the Sun is expected to be looking our way. Solar flux levels
are expected to decline to around the 110 mark but towards next
weekend levels should start to increase. Geomagnetic activity is
expected to be mostly quiet with no coronal hole disturbances and
coronal mass ejections expected. MUFs during daylight hours at equal
latitudes should be around 26MHz. Darkness hour lows are expected to
be about 14MHz. Paths this week to the Middle East should have a
maximum usable frequency with a 50 per cent success rate of around
24MHz. The optimum working frequency with a 90 per cent success rate
will be about 18MHz. The best time to try this path will be between
1000 and 1500 hours. Anytime now the start of the summer sporadic E
season is expected to commence.
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.
