Recently we had to skip a number in the bulletin numbering sequence.
If you think you are missing one, don't worry.

Solar flux was down an average four points last week relative to the
previous week.  Except for July 19, there have been no sunspots
visible for 11 days in a row.

Today should see the return of old region 7978 on the Sun, which
should bring a small rise in solar activity.  Look for solar flux to
gradually rise to near 80 by August 2, and then fall below 70 a week
later.  No geomagnetic upsets are expected from this region.

Sunspot Numbers for July 18 through 24 were 0, 0, 12, 0, 0, 0 and 0,
with a mean of 1.7.  10.7 cm flux was 66.8, 64.9, 66.1, 65.4, 65.1,
66, and 66.7, with a mean of 65.9.
