Solar flux last week was about the same as the week before.
Conditions were unsettled on March 2 and 3 and again on March 8,
with the A index in double digits.  Activity should continue low,
with the flux heading down to the mid 70s around February 12 through
14, and up to a peak near 86 around the 18th and the 19th and again
around March 2 and 3.  Look for active geomagnetic fields and
unsettled conditions due to recurring coronal holes from February 13
to 14 and again around the 25th through 27th.
 
Sunspot Numbers for February 2 through 8 were 76, 69, 63, 85, 55, 23
and 19, with a mean of 55.7.  10.7 cm flux was 86, 82.7, 86, 81.1,
84.3, 83.8 and 85.5, with a mean of 84.2.
 
The path projection this week is from Springfield, Illinois to Guam.
 
80 meters should be open from 0830 to 1300z, and 40 meters from 0730
to 1330.  Try 30 meters around 0930 to 1000 and again from 1430 to
1530.  20 meters may be open around 1530 to 1630 and with somewhat
weaker signals from 2030 to 2330.  Check 17 meters from 2100 to
2200.  On some days 15 meters may be open around the same period.
