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 288 Issued at 2200Z on 15 OCT 1997IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z SOLAR ACTIVITY WAS VERY LOW. YESTERDAY'S NEWLY NUMBERED
REGION 8096 (N14E51) PRODUCED A SUBFLARE AT 14/2115Z WITH SMALL
B-CLASS X-RAY OUTPUT, BUT HAS BEEN QUIET SINCE. TODAY'S NEW REGION,
8097 (N17E80) PRODUCED A BRIGHT SURGE AT 15/1508Z COINCIDING WITH A
B5.9 X-RAY OUTPUT. ALL OTHER REGIONS REMAINED QUIET. X-RAY IMAGERY
INDICATES A NEW REGION ROTATING THE EAST LIMB AT N15.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW FOR THE NEXT 3 DAYS WITH BOTH NEW REGIONS HAVING A SLIGHT
CHANCE OF PRODUCING C-CLASS ACTIVITY.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET FOR THE NEXT THREE DAYS. ISOLATED UNSETTLED
CONDITIONS ARE POSSIBLE DURING THE PERIOD.
