Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: 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 (07 May, 08 May, 09 May). IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 351 km/s at 05/2153Z. Total IMF reached 6 nT at 06/1804Z. The maximum southward component of Bz reached -4 nT at 06/1106Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 264 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (07 May, 08 May, 09 May). III.
