ARLP051 Propagation de KT7H

Solar activity was low last week.  Solar flux dropped to 83.8 on
December 17, the lowest since September 14.

Geomagnetic conditions were mostly stable.  The K index did go as
high as four, but only on a few occasions on the 16th, and once each
day on the 17th, 18th and 22nd.

Flux values should rise to 105 or higher in the first few days of
the new year, and then fall back to around 85 after the middle of
January.  There is a possibility of some disturbed conditions around
January 12.

Sunspot Numbers from December 16 through 22 were 29, 47, 51, 25, 53,
45 and 61, with a mean of 44.4.  10.7 cm flux was 84.5, 83.8, 85.1,
87, 91, 92.9 and 100, with a mean of 89.2.

The path projection for this week is for Christmas day, from Omaha,
Nebraska to Soviet Georgia.

80 meters looks good from 2000z to 0800z, with a weaker opening from
1130z to 1500z.  The best time is from 2330z to 0430z.  40 meters
should be open around the clock, with the best time from 2300z to
0500z, and the weakest signals from 1130z to 1200z and 1530z to
1630z.  30 meters should be best from 1330z to 1730z, 0400z to 0530z
and again around 0730z.  20 meters should be open around 1430z to
1600z, and there is a small chance of openings from 2130z to 2330z
and 0500z to 0730z.  The frequencies above 20 meters do not look
good over this path at this time of year.
