ARLP048 Propagation de KT7H

Solar flux still meanders listlessly in the seventies.  At least
over the past week geomagnetic disturbances were down, with K
indices as low as zero and one over many periods.  Look for fair
conditions over this context weekend, with no big surprises in
store.  We could see some disturbed conditions around the end of the
month, and again after December 11.

Sunspot Numbers for November 9 through 15 were 13, 19, 14, 11, 12,
13 and 28, with a mean of 15.7.  10.7 cm flux was 77.2, 78.1, 77.4,
76, 73, 75 and 76.6, with a mean of 76.2.

The path projection is for this Sweepstakes contest weekend, and
goes from Seattle to Oklahoma, Chicago and Miami and from Atlanta to
Dallas, San Francisco and Kansas.

From Seattle to Oklahoma, 80 meters should be good from 2300 to
1500z, and 40 meters nearly around the clock, with poor periods from
0330 to 0500 and around 1400 to 1500.  Check 20 meters from 1600 to
2300.  15 meters may be open from 1800.

From Seattle to Chicago, 80 meters should be open from 2230 to
1500z, 40 meters from 1500 to 2300 and again from 0030 to 0200.  20
meters looks good from 1530 to 2230.

From Seattle to Miami, check 80 meters from 2330 to 1230z, and 40
meters from 2130 to 0200.  20 meters looks good from 1600 to 2100.

From Atlanta to Dallas, 80 meters looks good from 2300 to 1430z.  40
looks good around the clock, with some bad periods around 1400.
Check 20 meters from 1530 to 1730 and again around 2000 to 2300.

From Atlanta to San Francisco 80 meters should be always open, with
40 meters closed from 0130 to 1600z.  Atlanta to Kansas looks good
for 80 meters around the clock, with the exception of 1600 to 2200.
Check 40 meters from 0000 to 0200 and 0800 to 1100 and 1530 to 2230.
20 meters should be open from 1630 to 2130.
