Average solar flux was up by only a few points last week.
Geomagnetic indices have also risen a bit, signaling some
instability.  Very low levels of solar activity should continue,
with a recurring coronal hole causing active geomagnetic conditions
around October 4 or 5.  Solar flux should rise to about 85 after the
first of the month, and then drop back to around 70 by October 17.
 
Sunspot Numbers for September 22 through 28 were 15, 17, 20, 35, 43,
36 and 35, with a mean of 28.7.  10.7 cm flux was 70.7, 71.4, 72.8,
76.2, 77, 74.7 and 74, with a mean of 73.8.
 
The path projection for this week is from Togo (5V) and Norfolk,
Virginia.
 
80 meters looks good from 2230 to 0600z, peaking around 0030 to
0500.  40 meters should be open from 2130 to 0700, and 30 meters
from 2030 to 0400, with 30 meters open as late as 0700 on many days.
20 meters should be open from 1700 to 0000, peaking toward the end
of the period.  Check 17 meters from 1330 to 2200, and 15 meters
from 1500 to 2000.  12 meters may be open on some days from 1530 to
2000.  10 meters does not look promising, but on rare occasions it
may be open some time between 1500 and 2100.
