Solar activity is still very low, although there were visible spots
on the Sun's surface every day this past week.  Average solar flux
was up about 3 points, and the A index was in the single digits.
Solar flux peaked up just over 70, and it is expected to drop below
70 around July 7, reaching back up to 70 again around July 17.
Around July 16 is when we could see a slight recurring geomagnetic
instability, although some smaller disturbances could appear also
around July 2, 3 and 14.

Sunspot Numbers for June 20 through 26 were 22, 33, 23, 23, 25, 23
