IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: Solar activity has been at low levels for the past 24 hours.
There are currently 5 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 (22 May, 23 May,
24 May).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 490 km/s at 21/1022Z. Total IMF reached 5
nT at 21/0000Z. The maximum southward component of Bz reached -4 nT at
21/0053Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2841 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (22 May, 23 May)
and quiet levels on day three (24 May).
