ARLP046 Propagation de K7RA

A single sunspot appeared on November 13-14, yielding a daily
sunspot number of 11 over both days. The sunspot number increased to
13 on the following day, November 15. The average daily sunspot
number for the reporting week (November 8-14) was 3.1, after no
sunspots during the previous seven days.

Average daily solar flux rose from 67.7 to 68.5. Average daily
planetary A index declined from 12 to 8.1, while average
mid-latitude A index shifted from 8.1 to 6.3.

There were no sunspots for 26 days, from October 18 to November 12.

Does this place us near the bottom of the sunspot cycle? Perhaps, or
somewhere toward it. Look at sunspot numbers in 2008-2009, during
the last solar minimum, and note the long periods with no sunspots:

Predicted solar flux over the next 45 days is 68 on November 16
through December 2, 69 on December 3-4, then 70, 69 and 69 on
December 5-7, then 70 on December 8-15, 69 on December 16, then 68
on December 17-29 and 69 on December 30.

Predicted planetary A index is 5 on November 16-17, 8 on November
18, 5 on November 19-24, 8 on November 25, 5 on November 26-30, then
15 and 30 on December 1-2, 10 on December 3-4, 8 on December 5-6, 12
on December 7-9, then 10 and 8 on December 10-11, 5 on December
12-27, then 15, 30 and 10 on December 28-30.

Spaceweather.com reported November 15-16 a geomagnetic unrest
prediction for November 18 or 19, although that is not reflected in
the forecast in the above paragraph. But the OK1HH forecast below
seems to agree with Spaceweather.com in this regard.

Geomagnetic activity forecast for the period November 16 through
December 12, 2018 from F.K. Janda, OK1HH.

"Geomagnetic field will be:
Quiet on November 16, 19, 26, 29-30, December 11-12
Quiet to unsettled on November 17, 20-21, 24, December 10
Quiet to active on November 22-23, 25, December 4-9
Unsettled to active on November 18, 27-28, December 1, 3
Active to disturbed on December 2

"Solar wind will intensify on November (17-23, 30) and on December
1-3, (4-6,) 7-9, (10)

"Parenthesis means lower probability of activity enhancement."

Steve Sacco, NN4X in Florida reported a Wednesday morning (November
14) 10 meter opening to Europe using FT8.
