Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a X1 event observed at
20/0028Z from Region 2242 (S19W44). There are currently 7 numbered
sunspot regions on the disk.
Solar Activity Forecast: Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (21 Dec, 22
Dec, 23 Dec).
Geophysical Activity Summary 19/2100Z to 20/2100Z: 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
406 km/s at 19/2212Z. Total IMF reached 7 nT at 20/1840Z. The maximum
southward component of Bz reached -6 nT at 20/0259Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 388 pfu.
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to major storm levels on day one (21 Dec), quiet to minor
storm levels on day two (22 Dec) and quiet to unsettled levels on day
three (23 Dec). Protons have a chance of crossing threshold on days one,
two, and three (21 Dec, 22 Dec, 23 Dec).
