:Product: 0610RSGA.txt :Issued: 2012 Jun 10 2200 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 162 Issued at 2200Z on 10 Jun 2012 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was moderate. Region 1504 (S18E51) produced an M1 flare at 10/0645Z and grew to end the period as a Dac type group with a beta magnetic configuration. New Regions 1506 (N11E66) and 1507 (S26E29) were numbered today and classified as Cao and Dao type groups, respectively, with beta type magnetic configurations. The remaining regions were generally stable. IB. Solar Activity Forecast: Solar activity is expected to range from low to moderate. An isolated M-class event is likely from Region 1504. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was generally at quiet levels. Wind speed at the ACE spacecraft was approximately 440 km/s through the period. The Bz component of the interplanetary magnetic field ranged between +/-4 nT. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period. IIB. Geophysical Activity Forecast: The geomagnetic field activity is expected to range from quiet to unsettled levels for the next three days (11-13 June) with a chance for an isolated active period on the first two days. A weak coronal hole high speed stream is expected on day one (11 June) and a glancing blow from the 08 June CME is expected on day 2 (12 June). Day three will see a return to mostly quiet conditions.
