Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 161 Issued at 2200Z on 09 Jun 2012

IA.  Analysis of Solar Active Regions and Activity from  08/2100Z
to 09/2100Z:  Solar activity was moderate. Region 1499 (N16W31) was 
the most active region producing two M-class x-ray events. The first
event was an impulsive M1 flare at 09/1132Z and the second was also
an impulsive M1/Sf event which occurred at 09/1645Z. Region 1499 
also produced several C1 events at 09/0308Z, 1032Z, and 1527Z.
Region 1499 was classified as a Cao type group with beta-gamma 
magnetic characteristics. New Region 1504 (S18E67) was numbered 
today and classified as a Cao type group with beta magnetic
characteristics. New Region 1505(S09E63) was also numbered today and 
classified as a Axx type group with alpha magnetic characteristics.
There were no earth-directed CMEs observed during the period.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
low with an increasing chance for occasional M-class activity for
the next three days (10-12 June).
IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field activity was mostly quiet. A weak disturbance
was observed on both ground and GOES magnetometers at 09/1841Z
leading to the single unsettled period of the day. Solar wind speed
at the ACE spacecraft continued to decline and ended the period near
440 km/s. The Bz component of the interplanetary magentic field
remained mostly neutral or positive. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels during the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the next three days (10-12
June) with the anticiapted glancing blows from CMEs on 06 June and
08 June and the arrival on 11 June of a coronal hole high speed
stream.
