Sunspots returned for a few days, on October 9 to 12, with sunspot
numbers of 24, 26, 15 and 15, respectively. No sunspot appeared on
the next day, but late on Wednesday Spaceweather.com reported a new
emerging Solar Cycle 25 spot on our Suns southeastern limb, and a
daily sunspot number of 12. NOAA Space Environment Center did not
report this, instead reporting the sunspot number at 0.  But the
next day the record was corrected and NOAA reported sunspot numbers
of 12 and 14 on October 14 and 15.  Average daily sunspot number
increased from 0 to 13.1, while average daily solar flux went from
71.8 to 73.1.  Geomagnetic indicators were lower, with planetary A
index dropping from 7.1 to 2.7 and middle latitude A index from 6 to
1.9.  Prior to October 9 there were no sunspots for two weeks, and
at that time a sunspot number of 13 on September 23 and 11 on
September 25.  Predicted solar flux for the next 45 days is 74 on
October 16 and 17, 72 on October 18 to 31, 70 on November 1 to 7, 73
on November 8 to 10, then 72, 71 and 71 on November 11 to 13, 70 on
November 14 to 23, 72 on November 24 to 27 and 73 on November 28 and
29.  Predicted planetary A index is 5 on October 16 to 19, then 10
on October 20, 8 on October 21 to 23, then 16, 38 and 38 on October
24 to 26, then 26, 15 and 10 on October 27 to 29, 5 on October 30
through November 6, 10 on November 7, 5 on November 8 to 15, then
10, 15 and 18 on November 16 to 18, 20 on November 19 and 20, then
24, 14 and 10 on November 21 to 23, 8 on November 24 and 25, and 5
on November 26 to 29.  Do you think the recent, or current, solar
minimum is lasting a little too long? Check out a contrarian view on

sunspot records and predictions from 1730 til 2101.  Dont ask me to
explain the numbers or how they were derived.  Ken Brown, N4SO
wrote, Evidence pointed to a very good propagation path to Asiatic
Russia, Japan, and to China on Saturday evening.  From October 10,
2330Z UA0, and first BV, 21.074 MHZ FT8 mode.  I first noticed UA0CA
calling CQ from Asiatic Russia. This is a rarity to see a UA0 on the
screen and so far I have never completed a contact. I have also
never completed a contact with China until Saturday evening.
Calling UA0CA from my station was noticed by BV1EK, China, and he
called me, and was able to complete a contact. At this same time
period, completed contacts with JA1FGX, JQ1CIV, and JG1SRB.  A
contact with UA0CA or with UA0ZK was not made, but I can appreciate
the distance is roughly 5000 miles away. I will try again on Sunday.
Distance to UA0ZK, for example, is 5391 miles.  For more information
concerning radio propagation, see the ARRL Technical Information
Service web page.  A detailed explanation of numbers used in this
bulletin is also available on this website.  An archive of past
propagation bulletins is also available.  Monthly propagation charts
between four USA regions and twelve overseas locations can be found
on the ARRL/Propagation web page.  Find better information and
tutorials on propagation on the k9la web site.  The multiple
websites mentioned in this bulletin can be found in teleprinter,
packet, and Internet versions of 2020 Propagation Forecast Bulletin
ARLP042.  Sunspot numbers for October 8 through 14, 2020 were 0, 24,
26, 15, 15, 0, and 12, with a mean of 13.1. 10.7 cm flux was 71.6,
73.1, 73.6, 72.9, 73.8, 72.3, and 74.5, with a mean of 73.1.
Estimated planetary A indices were 3, 2, 2, 3, 4, 3, and 2, with a
mean of 2.7. Middle latitude A index was 2, 1, 2, 2, 3, 3, and 0,
with a mean of 1.9.
