Problems with the PC and DSL connection mean a short bulletin for
this week.

Conditions were good over Field Day weekend, with no big geomagnetic
upsets. 40 meters was probably the best band all around for Field
Day contacts.

Sunspots and solar flux have been high recently, but both are
currently declining. Average sunspot numbers dropped over 48 points
from last week, and average solar flux was off nearly 17 points.

Currently geomagnetic conditions are very quiet, and are expected to
remain that way over the next week. Single digit planetary A indices
are forecast until after July 4. Solar flux is expected to decline
over the next few days, to 130 on Saturday, Sunday and Monday. Flux
is expected to rise to 160 by July 6 and 190 by July 11.

Sunspot numbers for June 21 through 27 were 212, 203, 228, 212, 220,
177 and 185 with a mean of 205.3. 10.7 cm flux was 200.3, 203.6
206.2, 194.8, 182.4, 167.9 and 147.9, with a mean of 186.2, and
estimated planetary A indices were 13, 7, 8, 10, 8, 13 and 10 with a
mean of 9.9.
