Topband reflector on the "27-Day Rotation" theory, I highlighted on
my desk calendar the week that followed by 25 days - this week. I
wanted to give that theory a try. As luck would have it, it worked!

         The best JAs may be yet to come.  Feb. 20-22 were
excellent and Feb 24 was not bad also.  Since February has
28 days, the 27.5 day cycle should fall on approximately the
same calendar dates in March.

         NOAA which also uses the 27.5 cycle is predicting a
period of low Aurora activity the next few days:
