ARLP032 Propagation de KT7H
 
Solar activity was down by a few points last week, with several days
of spotless Sun.  The sunspot number was zero on July 23, 24 and 25,
and solar flux was just below 70 all week.  The most unsettled
period was July 24, when the Boulder A index was 19, the Planetary A
index 28, and the highest K index was 5.
 
Solar flux is expected to stay fairly flat, but rise slowly toward a
broad peak around 85 from August 4 through 6.  Flux levels should be
back to current values after mid-August.  A recurring coronal hole
should bring stormy conditions around August 13.
 
Sunspot Numbers for July 20 through July 26 were 43, 26, 15, 0, 0, 0
and 11, with a mean of 13.6.  10.7 cm flux was 69.7, 68.5, 68.8,
68.5, 69.3, 69.7 and 69.4, with a mean of 69.1.
 
Path projection for this week is to Cocos-Keeling Island from
Southern California, Texas and Illinois.
 
For California, 80 meters should be open around 1200z and 40 meters
from 1100 to 1330.  Check 30 meters from 1030 to 1430 and 20 meters
around 0830 to 0930 and again from 1400 to 1700.
 
For Texas, check 30 meters from 1100 to 1230z, 20 meters from 1230
to 1430.
 
For Illinois, check 20 meters around 1300 to 1500z.
