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).
