Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 0 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low 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 levels for the past 24 hours. Solar wind speed reached a peak of 367 km/s at 08/0916Z. Total IMF reached 5 nT at 08/1218Z. The maximum southward component of Bz reached -3 nT at 08/1222Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 154 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (09 May, 10 May) and quiet to unsettled levels on day three (11 May). III.
