W1AW 2025 spring/summer operating schedule.  W1AW transmits morning
fast and slow code practice Tuesday through Friday at 1300z, or 9 am
edt.  Visitor operations are Monday through Friday from 1400 to
1945z, or 10 am to 345 pm edt.  The revolving schedule of code
practices and bulletins, both digital and phone, begin Monday
through Friday at 2000z, or 4 PM edt, until 0400z, or 12 am edt.
Audio from W1AWs CW code practices, CW/digital bulletins and phone
bulletin is available using EchoLink via the W1AW Conference Server
named W1AWBDCT.  The monthly W1AW Qualifying Runs are presented here
as well.  The audio is sent in real time and runs concurrently with
W1AWs regular transmission schedule.  All users who connect to the
conference server are muted.  Please note that any questions or
comments about this server should not be sent via the Text window in
EchoLink. Please direct any questions or comments via email to, w1aw
at arrl.org .  The weekly W1AW and monthly West Coast Qualifying
Runs are sent on the normal CW frequencies used for both code
practice and bulletin transmissions.  West Coast Qualifying Run
stations may also use 3590 kHz.  Please note a W1AW Qualifying Run
replaces a regularly scheduled code practice transmission on any
particular day and time.  The complete w1aw operating schedule may
be found on page 28 in the March 2025 issue of QST or on the web at,
www.arrl.org/w1aw .  Spaceweather.com is reporting A Hole In The
Suns Atmosphere that should reach Earth on March 9 and 10.  Solar
activity has been at moderate levels for the past 24 hours.  The
largest solar event of the period was a M1 event observed on March 5
at 1150z from Region 4016. There are currently 10 numbered sunspot
regions on the disk.  There is a chance for isolated minor solar
radiation storm levels throughout the period if any of the
returning/developing magnetically complex regions are active and
produce an event.  Geomagnetic field activity is expected to be at
quiet to unsettled levels on March 7 to 9, 19 to 24, and on March
29.  Active levels are expected on March 10 to 18, and then on March
25 to 28, with possible G1, Minor geomagnetic storm, conditions on
March 12 to 15 associated with recurrent negative polarity Coronal
Hole influences.  Weekly Commentary on the Sun, the Magnetosphere,
and the Earths Ionosphere, March 6, 2025, by F. K. Janda, OK1HH, The
combination of relatively low total solar activity and a larger
number of geomagnetic disturbances caused a worsening of shortwave
propagation conditions in February. However, the outlook for March
is better, not least because of the approaching equinox which occurs
on 20 March.  Solar activity will begin to increase more rapidly
after the larger sunspot groups return to the Suns disk, which is
the half of the Suns surface visible from Earth. At its eastern limb
we should see their activity as early as mid March. They will
approach the centre of the disk just around the Vernal Equinox on
March 20.  But even before that, the scenario may be somewhat
different. In the north west of the solar disk, we see a large
coronal hole, which is likely to be the source of a strong solar
wind that will probably affect the Earths ionosphere sooner than we
expect. But this too could be a harbinger of a further upsurge in
solar activity. So, within reason, all good news.  The forecast 10.7
centimeter flux for March 7 to 13 is 150, 150, 150, 155, 160, 170,
and 180, with a mean of 59.3.  The forecasted Planetary A Index for
March 7 to 13 is 5, 5, 8, 15, 15, 25, and 30, with a mean of 14.7.
The forecast Planetary K Index for March 7 to 13 is 2, 2, 3, 4, 4,
5, and 5, with a mean of 3.6.
