> This is an early bulletin because of the Thanksgiving holiday, but
> the timing is wrong for publishing another week of solar and
> geomagnetic data, so the numbers at the bottom of this bulletin are
> the same as in last week's Propagation Forecast Bulletin, ARLP047.
> An additional bulletin will come out on Monday, November 27 with the
> updated numbers.
> 
> Last weekend geomagnetic conditions were quiet for the ARRL Phone
> Sweepstakes. But we are about to experience the effects of a solar
> wind stream just before this next weekend's big contest, the CW
> portion of the CQ Worldwide DX Contest. The planetary A index for
> November 22-26 is predicted at 5, 10, 20, 15 and 10. Helioseismic
> holography has detected the emergence of a new large sunspot on the
> sun's far side.

> issue of QST for a good piece about "Solar Cycles and the Coming of
> Cycle 24," part 1. It was written by Jim Kennedy, K6MIO of the
> Gemini Observatory in Hilo, Hawaii, and gives good information on
> the magnetic conveyor belt, solar magnetic fields, and a 22 year
> solar magnetic cycle.
