The numbers looked better during this reporting week, October 5-11.

Average daily sunspot numbers rose from 128.6 to 144.1, and average
solar flux from 155.6 to 159.1.

Average daily planetary A index went from 9.1 to 7.6, and average
middle latitude A index from 8.9 to 8.3.

For some reason the middle latitude numbers were not available from
Fredericksburg, Virginia so we used the data from Boulder, Colorado.

Nine new sunspot groups emerged this week, with two on October 5,
one on October 7, two on October 8, one on October 9, another on
October 10, and two more on October 11.
