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 003 Issued at 2200Z on 03 Jan 2001

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

Solar activity was low. Several small C-class flares occurred, many of which were optically uncorrelated to active regions on the visible disk. The likely source of this activity remains an area at, or beyond, the northeast limb. C-class subflares also occurred in Regions 9289 (S07W25), 9290 (N29W60), and 9294 (N22E43).
IB. Solar Activity Forecast
Solar activity is expected to be low. Additional C-class activity is expected and there is a small chance of an isolated M-class flare.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field ranged from quiet to active levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to range from quiet to active levels during the three-day forecast period in response to a coronal hole stream.
