Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 137 Issued at 2200Z on 16 May 2016
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
16/1525Z from Region 2544 (N20W27). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on day one (17 May) and likely to be
low on days two and three (18 May, 19 May).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 567 km/s at 16/0113Z. Total IMF reached 8
nT at 16/1636Z. The maximum southward component of Bz reached -7 nT at
16/1154Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 2 pfu at 15/2315Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1269 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and three (17 May, 19 May)
and quiet to unsettled levels on day two (18 May).
