Sunspot numbers and solar flux softened over the past week, with
average daily sunspot numbers declining from 120.9 to just 37, and
average daily solar flux down from 122.7 to 93.8. These numbers
compare the October 1-7 activity against the previous seven days.

Average planetary A index was way up, from 5.1 to 24.3. The
planetary A index reading of 77 on Wednesday was a big factor in the
high average. That is a huge number, indicating a strong geomagnetic
storm.

Predicted solar flux for the near term is 80 on October 9-10, 85 on
October 11, 90 on October 12, 95 on October 13-14, 100 on October
15-16, 130 on October 17-18, 125 on October 19, 120 on October
20-25, 115 on October 26, 110 on October 27 and 100 on October
28-29.

Solar flux is predicted to decline to 85 on November 1-3, then rise
to 130 on November 12-14.
