Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 152 Issued at 2200Z on 01 Jun 2007
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity increased to moderate levels. New Region 960 (S06E73) was responsible for two M-class flares during the past 24 hours. An M1 x-ray flare occurred at 01/0651Z and an M2/Sf event occurred at 01/1459Z. A Tenflare of 100 sfu was associated with the M2 event. This region remains too close to the east solar limb to ascertain a complete magnetic analysis. Region 958 (S13E22) developed several sunspots during the period and is now classified a Bxo beta magnetic sunspot group. Region 959 (S12E49) contains two small umbra and was numbered today.
IB. Solar Activity Forecast: Solar activity is expected to be at moderate levels. Region 960 is likely to produce further M-class flare activity.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field was at quiet to unsettled levels. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on 02 June. Active conditions are expected on 03 and 04 June due to a recurrent coronal hole high speed stream.
