IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: 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 likely to be low with a
slight chance for an M-class flare on days one and two (20 May, 21 May)
and expected to be low with a chance for M-class flares on day three (22
May).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 655 km/s at 19/0854Z. Total IMF reached 7
nT at 19/1038Z. The maximum southward component of Bz reached -7 nT at
19/0733Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 3917 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and three (20 May, 22 May) and quiet
to unsettled levels on day two (21 May).
