ARLP022 Propagation de KT7H

Last week we reported that the solar flux for May 22 was 66.  For
those who keep records, It was actually 66.4.

There were no visible sunspots for the past six days, and solar
flux was down a couple of points.  Expect very quiet conditions to
continue, with very little solar activity.

Around June 8 a slightly rising solar flux should peak just above
70, and then fall below 70 after the middle of June.  The most
disturbed days over the next month are predicted to be around June
9 and 10, but with a predicted A index of only 12, so a major storm
is not expected.  This is from disturbed areas observed during the
last solar rotation coming back into view.

Sunspot Numbers for May 23 through 29 were 12, 0, 0, 0, 0, 0 and 0,
with a mean of 1.7.  10.7 cm flux was 67.2, 67.2, 66.9, 66.9, 66.6,
66, and 66.5, with a mean of 66.8.
