W1AW 2022 spring/summer operating schedule.  W1AW transmits morning
fast and slow code practice Tuesday through Friday at 1300z, or 9 am
et.  Visitor operations are Monday through Friday at 1400 to 1600z,
or 10 am to 12 pm et, and then from 1700 to 1945z, or 1 PM to 345 PM
et.  The revolving schedule of code practices and bulletins, both
digital and phone, begin Monday through Friday at 2000z, or 4 PM et,
until 0400z, or 12 am et.  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.  A slow coronal mass ejection has been observed late on 10
march, and event modeling suggests arrival at the Earth late on 13
March.  Increased geomagnetic activity is expected for 14 March
2022.  We observed an active Sun this week. Geomagnetic indicators
peaked on Saturday, March 5 when Alaskas high latitude college A
index reached 42.  Again this week, sunspots covered the Sun every
day. Average daily sunspot numbers rose from 44 to 87.4, and average
daily solar flux went from 98.5 to 115.5. Geomagnetic indicators
were also higher.  Average daily planetary A index increased from
7.3 to 11.4.  Predicted solar flux is 120 on March 11 and 12, 115 on
March 13, 110 on March 14 to 16, 105 on March 17, 100 on March 18 to
21, then 101 and 103 on March 22 and 23, 104 on March 24 to 27, then
110, 115 and 116 on March 28 to 30, 118 on March 31 through April 1,
120 on April 2, 116 on April 3 and 4, then 115 and 112 on April 5
and 6, 110 on April 7 to 9, then 108, 102, 98 and 99 on April 10 to
13 then 100 on April 14 to 17.  Predicted planetary A index is 12 on
March 11, 5 on March 12 and 13, then 10, 18, 15, 5 and 8 on March 14
to 18, then 12 on March 19 and 20, 15 on March 21, 7 on March 22 to
24, then 5, 10 and 8 on March 25 to 27, 5 on March 28 and 29, then
10, 12, 25, 20 and 10 on March 30 through April 3, 5 on April 4 to
6, then 15, 20 and 12 on April 7 to 9, and 5 on April 10 to 13, then
8 on April 14, and 10 on April 15 and 16.  OK1HH wrote, The power
density of solar radio noise at a wavelength of 10.7 cm, more
briefly referred to as solar flux, remains above 110 for a week.
Because we see two more active areas beyond the eastern limb of the
solar disk, thanks to the STEREO Ahead satellite, solar flux should
stay that way for another week.  The concurrence of increased solar
activity with seasonal changes during the approaching equinox
results in improved conditions for short wave ionospheric
propagation.  Occasional irregular occurrences of a slight increase
in geomagnetic activity, as was the case on March 5 and 6, cause
only a slight deterioration. Possible recurrent disturbance is
expected until the beginning of April, probably already in its first
days.  Sunspot numbers were 92, 77, 95, 82, 84, 93, and 89, with a
mean of 87.4. 10.7 cm flux was 110.9, 113.1, 120.1, 115.7, 118.3,
115.3, and 114.8, with a mean of 115.5.  Estimated planetary A
indices were 5, 10, 27, 18, 9, 6, and 5, with a mean of 11.4. Middle
latitude A index was 3, 7, 19, 13, 7, 5, and 4, with a mean of 8.3.
