This is an early propagation bulletin because of the Thanksgiving
holiday. There will be another bulletin on Monday, November 29,
which will summarize the solar flux, sunspot numbers and geomagnetic
A index for this week which normally appears at the end of this
bulletin.

A few days ago was the phone weekend of the ARRL Sweepstakes
Contest. Last weekend was not plagued by solar wind and the high
geomagnetic activity we experienced around November 7-12, although
there were some unsettled periods.

In a few days the CW weekend of the CQ Worldwide DX Contest begins,
and no big solar or geomagnetic effects are expected for this
contest weekend either.

The forecast calls for moderate geomagnetic conditions and a rising
solar flux. Flux values have been around 100 lately, but should rise
over the next few days.

Predicted solar flux is expected to peak at about 135 around
November 28-29, and for November 24-27 the expected values are 115,
120, 125 and 130.
