Cycle 24 Still Crackling

The Sun Today / July 03  Courtesy: nasa.gov
As poor as our latest solar cycle has been, there still seems to be plenty of life left. Now pegged as the weakest cycle in the past 100 years, edging out Cycle 14 of 1906.  This cycle, like its predecessors, has had a double peak....but, unlike the others, the second peak was stronger than the first. Initially predicted to peak with a SSN (smoothed sunspot number) of 70, this number was surpassed in October 2013, when the SSN reached 75.

The present rotation has brought a number of active sunspot groups into view along with several small solar flares. The elevated solar flux has had an immediate effect on propagation, producing excellent F2 conditions on the higher bands. Today's solar flux is pushing 170 and on the rise! It makes one wonder what other strange tricks Cycle 24 might have up her sleeve for us yet?

Active flaring during the summer 50MHz sporadic-e season can often produce some odd long-haul paths along with the possibility of some transcontinental auroral-e propagation....so hold on, as it looks like the ride is not yet over!
