ARLP029 Propagation de KT7H

Last week's solar flares never caused a big geomagnetic effect.  The
A index only went up to 10 on July 12.  The biggest upset recently
was early on July 17 when the K index went to 4 and the A index was
11.  This is hardly a disturbance, and is quite common during more
active portions of the solar cycle.

Solar flux has backed off from last week and is now below 70 again,
with the average down about five points from the week previous.

Solar flux is expected to rise to about 70 around July 26, and peak
below 80 around August 2.  No geomagnetic disturbances are forecast
at this time.

The main band for worldwide communication will be 20 meters over the
next month.

Sunspot Numbers for July 11 through 17 were 32, 19, 11, 0, 0, 0 and
0, with a mean of 8.9.  10.7 cm flux was 77, 73.7, 70.2, 67.8, 67,
66.9, and 66.8, with a mean of 69.9.
