Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was an M1 event observed at 07/1629Z from Region 2051 (S09, L=060). There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (08 May, 09 May, 10 May). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 374 km/s at 07/0043Z. Total IMF reached 5 nT at 07/1958Z. The maximum southward component of Bz reached -4 nT at 07/1958Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (08 May, 09 May) and quiet to active levels on day three (10 May). III.
