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.

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 304 Issued at 2200Z on 30 Oct 2000

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

Solar activity was low. The largest event during the period was a C4/1F from Region 9209 (S23E07) at 30/1350Z. Moderate growth was observed in Region 9212 (N07E46) since yesterday. No new regions were numbered.
IB. Solar Activity Forecast
Solar activity is expected to be low to moderate. Region 9209 and 9212 each have the capability to produce an isoloated M-class flare.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field ranged from quiet to minor storm. One period of minor storm conditions was observed from 30/0000 - 30/0300Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to mostly quiet to unsettled during the period. There is a chance of active to isolated minor storm conditions during the first day if an interplanetary shock arrives at the earth from the M4/2B event early back on 29 October.
