Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M5 event observed at 08/1007Z from Region 2056 (N04E44). There are currently 9 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 (09 May, 10 May, 11 May). IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 378 km/s at 07/2137Z. Total IMF reached 12 nT at 08/0732Z. The maximum southward component of Bz reached -11 nT at 08/0729Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (09 May, 11 May) and quiet to active levels on day two (10 May). III.
