Solar flux dipped below 100 last week.  Geomagnetic conditions were
stable most of the time, but there was one period around 1200z on
February 2 when the K index went as high as four.  Activity should
stay low, but increase again later this month.
 
WA4TTK has a new versions of his popular free solar activity
graphing program, including one for Windows.  Watch this bulletin
next week for more details.  In the meantime, you can get a free
copy by mailing a formatted MS DOS diskette of any size or format in
a postage paid return mailer to Scott Craig, 409 Jessie Drive,
Nashville, TN 37211.
 
Sunspot Numbers from January 27 through February 2 were 63, 60, 89,
81, 81, 55 and 52, with a mean of 68.7.  10.7 cm flux was 120.5,
119, 102, 99, 97.6, 94 and 96.3, with a mean of 104.1.
 
The projection for this week is from the center of the continental
United States to Peter 1 Island.

from 0530z to 0730z.  40 meters should be good from 0300z to 0930z,
and 30 meters from 0130z to 1130z.  20 meters should be open from
2330z to 0200z, and possibly until 0530z.  17 meters may be open
around 1430z to 1630z, and has a better chance from 2330z to 0130z.
