Activity increased a bit over the past week.   Solar flux was up 10
points on the average compared to the previous reporting period.
Geomagnetic indices varied from quiet to unstable.  The worst day
was July 2 when the K index reached five for several periods.

Look for solar flux to decline to about 75 around July 13, and then
rise again to about 90 around July 22 to 25.  Possible dates for
disturbances are July 16, 24 to 26, and August 1.

Sunspot Numbers from June 30 through July 6 were 50, 57, 68, 61, 57,
38 and 51, with a mean of 54.6.  10.7 cm flux was 82.6, 86.7, 82.8,
86.4, 84.6, 83.4 and 84, with a mean of 84.4.

The path projection for this week is from Boston, Massachusetts to
Greenland.

80 meters looks good from 0130z to 0630z, with the peak period
around 0400z.  40 meters looks good from 2230z to 1000z, peaking
around 0300z to 0500z.  Check 30 meters from 2030z to 1230z, with
the best time around 0100z to 0600z.  20 meters and above does not
look promising, but on some days 20 meters may be open around the
clock, except for the period from 0600z to 0900z.
