SDF Number 19 Issued at 2200Z on 19 Jan 2014

IA. Analysis of Solar Active Regions and Activity from 18-2100Z to 19-2100Z

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 19/0658Z from Region 1959 (S24E58). There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (20 Jan, 21 Jan, 22 Jan).
IIA. Geophysical Activity Summary 18-2100Z to 19-2100Z
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 329 km/s at 18/2355Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 317 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on days one and three (20 Jan, 22 Jan) and quiet to unsettled levels on day two (21 Jan).
