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 010 Issued at 2200Z on 10 JAN 1997IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z SOLAR ACTIVITY WAS VERY LOW. NO FLARES OCCURRED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MAJOR STORM LEVELS. STORM
CONDITIONS WERE OBSERVED AT MANY STATIONS FROM 10/0600-1200Z. THIS
ACTIVITY WAS IN RESPONSE TO SOLAR WIND CHARACTERIZED BY STRONG
SOUTHWARD IMF OVER A PERIOD OF SEVERAL HOURS. SOLAR WIND DATA FROM A
VARIETY OF SOURCES SUGGEST THE PASSAGE OF A MAGNETIC PLASMA CLOUD
WHICH FIRST ENCOUNTERED THE EARTH AT 10/0100Z. THIS CLOUD MAY BE
RELATED TO A LARGE CME OBSERVED BY THE SOHO SPACECRAFT ON 6 JANUARY.
WIND SPACECRAFT DATA SUGGEST THAT THIS STRUCTURE COMPLETED ITS PASS
BY THE EARTH BY ABOUT 10/1800Z. THE GEOMAGNETIC FIELD HAS BEEN QUIET
TO UNSETTLED SINCE ABOUT 10/1500Z. THE GREATER THAN 2 MEV ELECTRON
FLUX INCREASED FROM NORMAL TO HIGH LEVELS AT 10/1640Z AND HAS
REMAINED THERE.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
