Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 131 Issued at 2200Z on 11 May 2015
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
11/0409Z. There are currently 10 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 (12 May, 13 May,
14 May).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
400 km/s at 11/1108Z. Total IMF reached 12 nT at 10/2232Z. The maximum
southward component of Bz reached -10 nT at 10/2313Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on days one and two (12 May, 13
May) and quiet to unsettled levels on day three (14 May).
