Over the past reporting week (October 13-19) compared to the previous seven-day
average daily sunspot number declined from 55 to 31, while average daily solar
flux dropped from 101.9 to 83.4.
Planetary A index increased from 6.6 to
19.1, and average mid-latitude A index jumped from 5 to 14.
This is the
opposite of what happened two weeks ago compared to last week, when A indices
decreased but solar flux and sunspot numbers rose.
The latest prediction
for solar flux (from the October 20 prediction) shows these values: 75 on
October 21-23, 72 on October 24, 75 on October 25-26, 80 on October 27, 75 on
October 28-29, 80 on October 30, 85 on October 31 through November 5, 90 on
November 6-8, 85 on October 9-11, 80 on November 12-14, 75 on November 15-19, 70
on November 20-22, 75 on November 23-25, 80 on November 26 and 85 on November
27-30.
