11/10/2017
According to Spaceweather.com, 24 percent of 2017 so far (76 days) have seen zero sunspots. In all of 2016 there were only 32 days (9 percent) with no sunspots. There were no periods in 2015 with no visible sunspot activity.
Average daily sunspot number dropped from 17.7 last week to zero this week, November 2-8. Average daily solar flux declined from 75.4 to 70.8. Average daily planetary A index changed from 6.4 to 15.6, and average mid-latitude A index rose from 4.7 to 12.4.
Predicted solar flux is 66 on November 10-11, 68 on November 12-13, 70 on November 14-17, 75 on November 18-30, 72 on December 1, 71 on December 2-3, 70 on December 4-10, then 71, 72, 73, 73 and 74 on December 11-15, and 75 on December 16-24.
Predicted planetary A index is 28, 24, 12, and 8 on November 10-13, then 5, 16, 12 and 10 on November 14-17, 5 on November 18-19, 20 on November 20-22, 5 on November 23-28, 10 on November 29-30, 5 on December 1-2, 10 and 27 on December 3-4, 30 on December 5-6, then 28, 25 and 10 on December 7-9, 5 on December 10-11, 10 on December 12-14, 5 on December 15-16, 20 on December 17-19, and 5 on December 20-24.
Geomagnetic activity forecast for the period November 10 to December 6, 2017 from F.K. Janda, OK1HH of the Czech Propagation Interest Group compiling this geomagnetic activity weekly forecast since 1978.
“Geomagnetic field will be:
Quiet on November 13-14, 19, 24-28, December 2-3
Mostly quiet on November 18, December 1
Quiet to unsettled on November 16, 20, 23, 29
Quiet to active on November 12, 15, 17, 30, December 30, December 4, 6
Active to disturbed on November 10-11, 21-22, December 5
Amplifications of the solar wind from coronal holes are expected on November 11-15, (16-19,), 20-24, (29-30,) and on December (1-5,) 6-8.
No sunspots are visible so far in November, and as of November 9 we have seen nine days of blank sun. But the past few days had strong geomagnetic activity, with planetary A index on November 7-9 at 36, 47 and 20, and so far on early November 10, at 21. 28 is the predicted planetary A index for November 10.
