GOES hard proton rates are still low. Significant space weather can be expected in the next couple of days: A large full halo CME was associated with the M4.8 long duration event which began at 23:55 UTC on September 11 and peaked nearly one hour later. Although most of ejected material was observed over the east limbs, Earth will receive an impact from at least the outer leading edge of this CME and perhaps even from a part of the core CME. Solar Activity Forecast: Solar activity is expected to be at low to moderate levels. Region 672 remains capable of producing isolated low level M-class flares, and has a slight chance of producing a major event. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on 13 September through much of 14 September. Late on 14 September a shock passage from the long duration M4 flare mentioned in IA is anticipated. Major to severe storming may likely occur following the onset of the shock and dominate the first half of the period on 15 September. Further, a recurrent high speed coronal hole stream is also expected to become geoeffective on 15 September and continue into 16 September.
