The listing of solar indices for the past week will be delayed
until bulletin ARLP001 on January 3. We can say though that the
solar flux wound down over the past week after the fading movement
across the Sun of region 7999. Flux is expected to decline to the
low seventies over the next few days, and then should rise again
around January 4 to a peak in the mid eighties around January 14.
The A and K indices have been low, except for an instability on
December 23 where the planetary K index rose to four. A and K
indices are expected to remain stable, with a slight rise to an A
index of 15 around January 6.
Having just passed the longest night of the year, expect 160, 80 and
40 meters to be at their best over the hours of darkness. 20 meters
remains the best band for worldwide coverage during daylight and a
couple of hours after sunset.
