SDF Number 97 Issued at 2200Z on 07 Apr 2015
IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (08 Apr, 09 Apr, 10 Apr).
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 543 km/s at 07/0318Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 496 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (08 Apr), quiet to minor storm levels on day two (09 Apr) and quiet to active levels on day three (10 Apr).
