Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 149 Issued at 2200Z on 29 May 2017
IA. Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: 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
28/2313Z from Region 2659 (N13W70). 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 day one (30 May) and expected to
be very low on days two and three (31 May, 01 Jun).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 405 km/s at 29/1206Z. Total IMF reached 17
nT at 29/0908Z. The maximum southward component of Bz reached -13 nT at
29/1241Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 490 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (30 May) and quiet levels
on days two and three (31 May, 01 Jun).
