ARLP048 Propagation de K7RA

This is a short propagation bulletin sent out early due to the
Thanksgiving holiday. ARRL headquarters will be closed on Friday,
the day after the holiday in addition to Thanksgiving Day.

Friday is when the new weekly bulletin is normally transmitted.
Sunspot numbers, solar flux and A indices for November 20-26 will
appear in a subsequent bulletin early next week.

Solar flux and sunspot numbers are expected to run slightly lower
than now. Solar flux for the past week has been running from 171 to
178, and for the CW weekend of the CQ Worldwide DX Contest (November
29-30), values should run 15 to 20 points lower. After settling down
over the next two days, geomagnetic conditions are expected to be
quiet, which should be great news for contesters.

For a last minute propagation assessment before the weekend, check
the NW7US site at http://www.hfradio.org/propagation.html.

Also, check http://spaceweather.com/ to see which way the
interplanetary magnetic field is pointing. If it is pointing north
(shown just below the sunspot number to the left side of the page)
conditions should be fairly quiet and stable, even if there is a
strong solar wind.
