Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 211 Issued at 2200Z on 30 Jul 2014
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 C9 event observed at
30/1617Z from Region 2127 (S09E36). There are currently 9 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (31 Jul, 01 Aug,
02 Aug).
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, as measured by the ACE spacecraft, reached a peak speed of
358 km/s at 30/0148Z. Total IMF reached 5 nT at 30/0333Z. The maximum
southward component of Bz reached -5 nT at 30/0244Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (31 Jul, 01 Aug) and quiet to
unsettled levels on day three (02 Aug) with a chance for active
conditions.
