Report of Solar Geophysical Activity
Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 14 Issued at 2200Z on 14 Jan 2016 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (15 Jan, 16 Jan, 17 Jan). IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: 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 597 km/s at 14/0303Z. Total IMF reached 5 nT at 13/2106Z. The maximum southward component of Bz reached -5 nT at 14/0148Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2836 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (15 Jan, 16 Jan, 17 Jan). III.
