Solar Activity

.24 hr Summary...
Solar activity was at very low levels. Region 2597 (S14W83, Hsx/alpha)
continued to decay as it rotated towards the SW limb, leaving a nearly
spotless solar disk. Analysis of the CME first observed in SOHO/LASCO
imagery departing the SW limb at 29/2012 UTC, indicated a trajectory
well west of the Sun-Earth plane. No impacts at Earth are expected from
this CME. No Earth-directed CMEs were observed in available coronagraph
imagery.

.Forecast...
Solar activity is expected to remain at very low levels all three days
of the forecast period (30 Sep-02 Oct).
