Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: 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 (14 May, 15 May, 16 May). IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 327 km/s at 13/0643Z. Total IMF reached 5 nT at 12/2226Z. The maximum southward component of Bz reached -4 nT at 12/2147Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 145 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (14 May, 15 May, 16 May). III.
