ARLP046 Propagation de K7RA

This was one of those confounding weeks when the average daily
sunspot number was down, while the average daily solar flux rose.
Compared with the previous seven days, for November 6 to 12 average
daily sunspot number declined 10.7 points to 85, while average daily
solar flux rose 11.5 points to 139.4.

The latest prediction from the USAF/NOAA 45 day outlook has solar
flux at 165 on November 14, 180 on November 15 and 16, then 185,
190, 195, 200 and 195 on November 17 to 21, then 190, 170, 150, 135
and 125 on November 22 to 26, 105 on November 27 and 28, 100 on
November 29 and 30, 90 on December 1 to 3, and bottoming out at 80
on December 5. It then rises to a short term maximum of 200 on
December 16 and 17 before dropping below 100 by the end of the year.

Predicted planetary A index is 8 on November 14 and 15, 12 on
November 16 to 18, 10 on November 19, 8 on November 20 and 21, 12 on
November 22 to 24, 8 on November 25, and 5 on November 26 to 29. It
then rises to a high of 22 on December 6 and again on December 26.

Petr Kolman, OK1MGW of the Czech Propagation Interest Group has a
geomagnetic forecast for us. He sees the geomagnetic field quiet to
unsettled November 14 and 15, active to disturbed November 16, quiet
to active November 17 to 19, mostly quiet November 20 and 21, quiet
to active November 22, quiet to unsettled November 23 and 24, quiet
to active November 25, mostly quiet November 26, quiet November 27
to 30, active to disturbed December 1, quiet on December 2 and 3,
quiet to unsettled December 4 to 6, quiet to active December 7,
quiet to unsettled December 8, and mostly quiet December 9 and 10.

Pete Heins, N6ZE of Thousand Oaks, California sent this report of a
six meter opening:

"There was an extensive F-2 opening on Monday afternoon, 10 November
2014.

I worked ZL1RS (6470 mi) in New Zealand and CX7CO (6259 mi) in
Uruguay. I also had a QSO with KH6HI (2537 mi) near Honolulu, HI for
new grid, BL01, on 6 meters from my DM04ne QTH in SoCal."

Later he wrote, "Actually I discovered that I have worked BL01 in
the past! I run 100w to a 5 element yagi about 15 feet above ground
level with lots of nearby obstructions."

Jon Jones, N0JK of Lawrence, Kansas wrote about the same six meter
opening:

"On the afternoon of November 10, the 6 meter band opened between
Hawaii and the mainland states starting around 2000z.

I worked Jim KH6/K6MIO grid BK29 at 2132z from Lawrence, KS on
50.120 MHz.

I received a "5x2" report from Jim. He had a big pileup calling and
heavy QSB - up well over S-9 then down in the noise then back. Also
heard him work fellow locals N0CWR and N0XA. I heard KH6U on 50.115
but very weak.

I had been out with our 3 year old grand daughter at a church
playground in Lawrence that afternoon to let her play. It was so
nice out, 74 degrees F and sunny. I checked my cell phone while
watching her and saw the spots for the Hawaiian stations on 6.
Packed her up and back home - we live 5 minutes away. I listened
first on the home setup - (dipole in attic) and heard K6MIO/KH6 on
50.120. Figured better to try for a contact from home than go out
portable and possibly lose propagation. I had just moved the dipole
to favor propagation to the Pacific rather than South America last
week. After I worked Jim I went out portable. Jim was Q5, S1 to 2 on
just a whip. But band dropped by the time I got the yagi up. Missed
KH7Y while I was putting the antenna and masts in the car. KH7Y
worked N0XA and N0CWR (plus many others).

First F2 opening from the Midwest to Hawaii in solar cycle 24. The
last one I worked was November, 2001. The geomagnetic field was
active on the 10th."

Here is another article with an update on that recent monster
sunspot:

In this video, it looks to me like the sun is rotating backward,
although a reader comment shows that at least one reader sees it
rotating in the correct direction, left to right.

Don't forget the ARRL SSB Sweepstakes this weekend. Details are
here: http://www.arrl.org/sweepstakes

Here is a YouTube recording of WA2TPU working a couple of stations
in South Africa running 5 watts, although it is not clear if they
are on 15 or 20 meters.

11.6. Estimated mid-latitude A indices were 8, 10, 8, 8, 16, 9, and
6, with a mean of 9.3.
