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 029 Issued at 2200Z on 29 JAN 1997IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z SOLAR ACTIVITY WAS VERY LOW. NEW REGION 8015 (N07E33),
A SIX SPOT 'BXO' GROUP, WAS NUMBERED TODAY, AND IT PRODUCED THREE
B-CLASS EVENTS, THE LARGEST AN OPTICALLY CORRELATED B5.8 FLARE AT
1917Z. REGION 8014 (S15W04) HAS DECAYED INTO A SPOTLESS PLAGE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW.

THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED FOR THE PAST 24
HOURS, WITH CONDITIONS PREDOMINATELY QUIET SINCE 29/0900Z. THE
GREATER THAN 2 MEV ELECTRONS EXCEEDED VERY HIGH LEVELS FOR THE FIRST
TIME AT 29/1752Z, AND HAVE REMAINED IN THE VERY HIGH RANGE SINCE
29/1905Z.
IIB. Geophysical Activity Forecast
GEOMAGNETIC ACTIVITY IS
EXPECTED TO BE MOSTLY QUIET FOR THE NEXT THREE DAYS, WITH THE
POSSIBILITY FOR ISOLATED PERIODS OF UNSETTLED CONDITIONS.
