Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 62 Issued at 2200Z on 03 Mar 2014

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

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 03/1558Z from Region 1989 (N08W42). There are currently 10 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (04 Mar, 05 Mar, 06 Mar).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
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 377 km/s at 03/0029Z. Total IMF reached 5 nT at 03/0245Z. The maximum southward component of Bz reached -4 nT at 03/0114Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 12 pfu at 02/2105Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on days one, two, and three (04 Mar, 05 Mar, 06 Mar). Protons have a slight chance of crossing threshold on days one, two, and three (04 Mar, 05 Mar, 06 Mar).
