Sun numbers from the ARRL propagation letter.

Quote
Recent solar activity took a healthy jump this week, with the
average daily sunspot number increasing nearly 48 points to 126.9, a
positive change of 60 percent compared to the previous week. Average
daily solar flux was up 16.4 points to 126.5.

The daily sunspot number rose to 148 on October 15, then 166 on
October 17, the highest it's been since May 15-17 when it was 186,
212 and 198.

The average planetary A index was unchanged at 8.1. The high
latitude college A index indicated active geomagnetic conditions on
October 14-15, when it was 31 and 27.

The latest prediction shows solar flux at 135, 130 and 120 on
October 18-20, 115 on October 21-23, 110 on October 24-25, 100 on
October 26-29, 105 on October 30-31, 100 on November 1-2, 110 on
November 3-4, 115 on November 5, 120 on November 6-7, and 125 on
November 8-12.

The predicted planetary A index is 8 on October 18, 5 on October
19-20, 12 and 10 on October 21-22, 5 on October 23 through November
10, 12 on November 11, 5 on November 12-16 and 8 on November 17-19.


If the prediction is correct, the numbers are to drop off some after peaking on the 18th. Lets hope the prediction is wrong.
