Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 242 Issued at 2200Z on 30 Aug 2017
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 C5 event observed at
30/1845Z from Region 2674 (N14E64). There are currently 3 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 and a slight chance for an M-class
flare on days one, two, and three (31 Aug, 01 Sep, 02 Sep).
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 408 km/s at 30/0012Z. Total IMF reached 10
nT at 29/2100Z. The maximum southward component of Bz reached -4 nT at
30/0112Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at active to minor storm levels on days one and two (31 Aug, 01
Sep) and unsettled to active levels on day three (02 Sep).
