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 C5 event observed at
16/1140Z from Region 2242 (S19E11). There are currently 9 numbered
sunspot regions on the disk.
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
(17 Dec, 18 Dec, 19 Dec).
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, as measured by the ACE spacecraft, reached a peak speed of
487 km/s at 16/0214Z. Total IMF reached 7 nT at 15/2103Z. The maximum
southward component of Bz reached -6 nT at 16/1235Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 958 pfu.
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (17 Dec,
18 Dec, 19 Dec). Protons have a slight chance of crossing threshold on
days one, two, and three (17 Dec, 18 Dec, 19 Dec).
