ARLP006 Propagation de KT7H

Solar activity is still very low.  There were five days over the
past week with no sunspots, and those days also had solar flux of
74 or lower, which is the average flux for the past 90 days.

Don't expect any change at any time soon.  Solar flux will continue
low along with low geomagnetic indices.  There may be a slight
disturbance this weekend, but the A index shouldn't rise much above
10.  Solar flux may rise toward the mid-seventies around the and of
this month.

The NOAA Space Environment Service Center has a very nice web site
with lots of solar images and historical solar data.  You can find
it at http://www.sel.noaa.gov.  The images of the sun are quite
nice, but they should be a lot more interesting in a few years when
they are covered with spots.

Sunspot Numbers for February 1 through 7 were 15, 15, 0, 0, 0, 0
and 0, with a mean of 4.3.  10.7 cm flux was 75.1, 76.4, 74, 73.5,
71.4, 71.2 and 70.1, with a mean of 73.1.
