Average daily sunspot numbers hardly changed from last week and the
week prior, but average daily solar flux bounced back to about the
level it was from two weeks ago.  Average daily sunspot numbers were
down five points to 50.7, and average daily solar flux was up 7.7
points to 106.4.  Predicted solar flux values are 105 on February 8
to 10, 110 and 105 on February 11 and 12, 100 on February 13 and 14,
110, 115 and 110 on February 15 to 17, 115 on February 18 and 19,
110 on February 20 and 21, 105 on February 22, 115 on February 23
and 24, then 110, 105 and 100 on February 25 to 27, 95 on February
28 through March 2, 115 on March 3 and 4, 120 on March 5 and 6, and
125 on March 7 and 8.  The predicted planetary A index is 22, 15 and
10 on February 8 to 10, 5 on February 11 to 18, 8 on February 19, 5
on February 20 and 21, then 15, 10 and 8 on February 22 to 24, 5 on
February 25 to 28, 10 and 8 on March 1 and 2, 5 on March 3 to 7, and
8 on March 8 and 9.  OK1HH says geomagnetic activity should be quiet
to unsettled on February 8, quiet to active February 9 and 10, quiet
to unsettled February 11 and 12, quiet to active February 13 and 14,
quiet to February 15 and 16, quiet February 17 to 21, active to
disturbed February 22 and 23, quiet to unsettled February 24 and 25,
quiet on February 26 and 27, mostly quiet February 28, quiet to
active March 1, quiet to unsettled March 2, and mostly quiet on
March 3.  Ive been looking at the predictions for planetary A index
and solar flux, and it is interesting to note how they change over
time.  The planetary A index prediction for February 3 for over a
month was a value of 5, until January 31, when it changed to 18.
Then on February 1 it was 15, and the same on February 2.  But on
February 3, the actual value was 4.  A similar thing happened with
the February 4 prediction. It was 5 up until January 31, when it
changed to 15, then for March 1 and 2 it was 12, then it changed
back to 15 on March 3.  The following day, March 4, the actual value
was 4 again, just as it was the day earlier.  Bill Bliss, W1WBB of

Sunspot numbers were 47, 65, 54, 79, 30, 41, and 39, with a mean of
50.7. 10.7 cm flux was 102.7, 103.7, 111.8, 111.1, 106.7, 105.1, and
103.5, with a mean of 106.4.  Estimated planetary A indices were 1,
4, 9, 4, 4, 2, and 2, with a mean of 3.7. Estimated mid latitude A
indices were 1, 4, 9, 6, 3, 2, and 2, with a mean of 3.9.
