Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M8 event observed at
17/0451Z from Region 2242 (S18W01). 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
(18 Dec, 19 Dec, 20 Dec).
Geophysical Activity Summary 16/2100Z to 17/2100Z: 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
454 km/s at 17/0219Z. Total IMF reached 6 nT at 17/1503Z. The maximum
southward component of Bz reached -5 nT at 17/0248Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 653 pfu.
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (18 Dec) and quiet to
active levels on days two and three (19 Dec, 20 Dec). Protons have a
slight chance of crossing threshold on days one, two, and three (18 Dec,
19 Dec, 20 Dec).
