Solar activity report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

SDF Number 350 Issued at 2200Z on 15 Dec 2000

IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z

Solar activity was low. Maximum activity continues to be sporadic minor C-class events.
IB. Solar Activity Forecast
Solar activity is expected to be low, with the chance for an isolated M-class event.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field has been quiet at all latitudes for the past 24 hours. The greater than 2 MeV flux continued its recent daily fluctuation between low and moderate levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be low, with isolated periods of unsettled conditions, for the next three days.
