sunspot groups appeared on March 1, another one on March 2, three
more on March 3, one more on March 5, two more on March 6, and
another on March 7, then two more on March 9.  Average daily
planetary A index declined from 27.7 to 14.6, and average middle
latitude numbers went from 18.9 to 10.7, reflecting the quieter
conditions following the upset the week before.  The Penticton
observatory, the source for solar flux data is way up at 49.5
degrees north longitude, in eastern British Columbia. For much of
the year the Sun is low in the sky, so all winter they do their
thrice daily readings at 1800, 2000 and 2200 UTC. But on March 1
they shifted over to 1700, 2000 and 2300 UTC. The local noon, 2000
UTC, reading is the official solar flux for the day.  You can see
the data and the dates on //www.spaceweather.gc.ca/ .  The Vernal
Equinox, when the northern and southern hemispheres are bathed in
equal solar radiation is less than two weeks away.  Predicted solar
flux shows values peaking now, and again on March 16 to 19.  Flux
values are expected at 178, 175, and 170 March 10 to 12, 172 on
March 13 and 14, 170 on March 15 and 16, 180 on March 17 and 18,

and 14, then 175, 170 and 165 on April 15 to 17.  Predicted
planetary A index is 8, 8, 10 and 8 on March 10 to 13, 5 on March 14
and 15, 8 on March 16 and 17, then 5, 8 and 16 on March 18 to 20, 5
