Solar activity continues to drift into the low part of the cycle.
Flux was below the average for the previous 90 days on every day
over the past week.  Flux is expected to gradually drift up to a
plateau around 75 between August 28 and September 3, then drop back
around 70 after the first week in September.  Expect a moderately
active geomagnetic field around September 5, 6, and 10 due to
recurrent coronal holes.
 
The latest prediction for the rest of this solar cycle shows a
slight rise in solar flux this fall before the bottom of the cycle
around June through December, 1996.  Flux should be back up around
current levels around April, 1997.  The peak in solar flux for the
next cycle is projected for August, 2000.
 
For sunspot numbers the expected minimum is around April to June,
1996.
 
Sunspot Numbers for August 10 through August 16 were 24, 22, 12, 11,
0, 38 and 41, with a mean of 21.1.  10.7 cm flux was 73, 72.9, 71.9,
70.8, 70.1, 71.4 and 70.5, with a mean of 71.5.
