This is the last propagation bulletin for 1995.  After this week the
author will be on vacation in the state of Bahia in Brazil until the
new year.  The next bulletin will be for January 5, 1996.

Solar activity last week was unchanged when compared to the previous
week with an identical average solar flux of 73.4.  Geomagnetic
conditions were stable, with K indices of zero or one over many
periods.

Don't look for much change over the next month.  We are near the
bottom of this solar cycle, and there just aren't any active solar
regions that should cause any change.  One exception is on December
24 when a recurring coronal hole should provide some geomagnetic
instability, with rising A and K indices.  The effect should fade
over the last week of the month.  Otherwise look for solar flux to
continue to meander around the low seventies.

Sunspot Numbers for December 7 through 13 were 14, 11, 29, 25, 29,
15 and 15, with a mean of 19.7.  10.7 cm flux was 74.1, 74.1, 73.9,
73.5, 73.4, 72.3 and 72.6, with a mean of 73.4.
