ARLP051 Propagation de KT7H

Solar activity was up very slightly last week when compared to the
week previous.  Solar flux below the average for the previous 90
days on every day through the week.  Geomagnetic conditions have
been stable, with the December 4 the most active day.  K indices
were as high as five and the A index was 16.  Otherwise most days
have had K indices of zero and one.

Conditions are expected to remain about the same, with solar flux in
the low seventies and low geomagnetic activity.  A recurring coronal
hole is expected to cause a mild upset around December 26 and again
around December 31, but the A index is expected to remain below 20
on both days.

Next week will be the last propagation bulletin for the year,
because the author will be vacationing in Brazil until January 3.

Sunspot Numbers for November 30 through December 6 were 17, 16, 16,
23, 22, 22 and 15, with a mean of 18.7.  10.7 cm flux was 74.3,
72.7, 73.3, 73.3, 72.8, 73.6 and 74, with a mean of 73.4.
