Solar flux is rising gradually in the short term.  The average flux
last week was about 7 points higher than for the week previous.  A
week as reported in this bulletin runs from Thursday through
Wednesday.  The bulletin is written on Thursday, and it is released
on Friday.
 
Geomagnetic conditions have been very quiet and stable, although
there was an upset on July 1 with the K index rising as high as
four.  Conditions are expected to remain stable until July 16 and
17, when we could see a somewhat disturbed period, and again around
July 23 as well.  July 30 could produce some very disturbed
conditions with K indices of five and A index around 30.  Solar flux
is currently rising, and may peak at 90 around July 16 through 18.
Flux values should reach minimum again at the end of the month.
 
Sunspot Numbers for June 29 through July 5 were 38, 45, 43, 41, 20,
32 and 32, with a mean of 35.9.  10.7 cm flux was 77.5, 78.1, 78.8,
77.7, 78.1, 80.8 and 80.2, with a mean of 78.7.
 
The path prediction for this week is from the center of the
continental United States to Bolivia.
 
80 meters should be open from 0130 to 1030z, 40 meters from 0100 to
1100 and  30 meters from 2330 to 1200.  Check 20 meters from 2100 to
0400, and expect less stable conditions until 0800, with another
opening from 1100 to 1400.  17 meters should be open on most days
from 1800 to 0300, with signals increasing during that period.  15
meters does not look promising at this time, but your best bet is
around 0200 to 0300.  Although unlikely, the best chance of a 10 or
12 meter opening is over that same period.
