Propagation and Monitoring Report

No sunspots have been observed in the period November 18 to 26.

According to the ARRL, we had our last glimpse of sunspot group 1008 as it was about to slip over our sun's western horizon on November 18. No sunspots have emerged since then, but it seems a reasonable assumption that we will see more cycle 24 spots, but we do not know when. There is a prediction from USAF/NOAA that shows solar flux rising to 70 on December 8-9, and perhaps this is just tracking a possible reappearance of the region that birthed sunspot group 1007, which we saw in the sun's southern hemisphere from October 30 through November 6.

Propagation into Melbourne continues to be very good during our mid afternoon period, 0300-0500, with many shortpath signals from the Middle East, Europe, and Africa on 19 metres, and long path from the same regions on 49, 41, 31, 22 and 25 metres.
