Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 142 Issued at 2200Z on 21 May 2016
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.
The largest solar event of the period was a C1 event observed at
21/1400Z from Region 2546 (S07W21). There are currently 1 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-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 minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 545 km/s at 21/0520Z. Total IMF
reached 11 nT at 21/0541Z. The maximum southward component of Bz reached
-9 nT at 21/0630Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 612 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (22 May), quiet to
unsettled levels on day two (23 May) and quiet levels on day three (24
May).
