Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 89 Issued at 2200Z on 30 Mar 2018
IA. Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
30/0804Z from Region 2703 (S08E60). There are currently 1 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (31
Mar, 01 Apr, 02 Apr).
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 454 km/s at 30/0322Z. Total IMF reached 8 nT at
30/1654Z. The maximum southward component of Bz reached -4 nT at
30/1738Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 14850 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (31 Mar) and quiet levels
on days two and three (01 Apr, 02 Apr).
