After a grueling 51 day period with no sunspot groups a small solar cycle 24
sunspot group has emerged in the northern and western hemisphere of the Sun.
Hopefully it will survive long enough to be numbered by NOAA/SWPC.
As a side note yesterday evening we experienced an unexpected brief (3 hrs)
but moderately strong (Kp-6) geomagnetic storm. It did not come from a
geo-effective (Earth facing) sunspot group associated coronal mass
ejection. The likely source of the geomagnetic storm was a collapsing solar
filament on the Sun or and unidentified deep space (out of our solar system)
source.
My forecast for the above mentioned period of 08/29-09/01/2009 was a Kp 0-2
(quiet), isolated 3 (unsettled).
