ARLP002 Propagation de KT7H

Solar activity was up a bit last week, while geomagnetic activity
was quite low.  This is a nice combination for HF propagation,
giving us a little better conditions on higher frequencies while
absorption is lower.

Low activity is expected to continue, with a gradually declining
solar flux rising slightly again after January 22.  A recurring
coronal hole is expected around January 20, but it should not cause
a great disturbance.

Sunspot Numbers for January 4 through 10 were 48, 69, 57, 45, 53,
27 and 13, with a mean of 44.6.  10.7 cm flux was 85.9, 84.9, 82.7,
82.5, 79.3, 75.9 and 73.8, with a mean of 80.7.
