*CRACKLING SUNSPOT: *Giant sunspot 978 is crackling with
C-class<http://www.spaceweather.com/glossary/flareclasses.html?PHPSESSID=3135qlfndao37f3e1a9nb54924>solar
flares, unleashing five in the past 24 hours alone. Yesterday, in the
hills overlooking Los Angeles, California, Gary
Palmer<gp  thesuninmotion.com>caught the spot in mid-eruption:

Palmer recorded an entire movie of the eruption--"IMAX-style," he says.
