Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 48 Issued at 2200Z on 17 Feb 2013
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
17/1550Z from Region 1675 (N12E18). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at low
levels on days one, two, and three (18 Feb, 19 Feb, 20 Feb).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: 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
403 km/s at 16/2302Z. Total IMF reached 9.5 nT at 16/2101Z. The maximum
southward component of Bz reached -7.3 nT at 17/1417Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels for the next three days (18 Feb, 19 Feb,
20 Feb).
