Report of Solar Geophysical Activity (RSGA)
Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 1 Issued at 2200Z on 01 Jan 2014 IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M9 event observed at 01/1852Z. There are currently 7 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a chance for X-class flares on days one, two, and three (02 Jan, 03 Jan, 04 Jan). IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: 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 607 km/s at 01/2100Z. Total IMF reached 17 nT at 01/1334Z. The maximum southward component of Bz reached -13 nT at 01/1334Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (02 Jan) and quiet to unsettled levels on days two and three (03 Jan, 04 Jan). Protons have a slight chance of crossing threshold on days one, two, and three (02 Jan, 03 Jan, 04 Jan). III.

Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: 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 02/0233Z from Region 1944 (S08E64). There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a chance for X-class flares on days one, two, and three (03 Jan, 04 Jan, 05 Jan). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 666 km/s at 02/2059Z. Total IMF reached 10 nT at 01/2155Z. The maximum southward component of Bz reached -6 nT at 02/0152Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1780 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (03 Jan, 04 Jan) and quiet levels on day three (05 Jan). Protons have a slight chance of crossing threshold on days one, two, and three (03 Jan, 04 Jan, 05 Jan). III.
