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 026 Issued at 2200Z on 26 JAN 2000

IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z

SOLAR ACTIVITY WAS LOW. THREE LOW-LEVEL C-CLASS EVENTS OCCURRED DURING THE PERIOD. ONE WAS A LONG DURATION C1 AT 26/1157Z THAT WAS NOT OPTICALLY CORRELATED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW FOR THE FORECAST PERIOD.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO ACTIVE LEVELS DURING THE LAST 24 HOURS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT QUIET TO UNSETTLED CONDITIONS THE FIRST DAY OF THE FORECAST. ACTIVE CONDITIONS ARE EXPECTED FOR THE REMAINDER OF THE PERIOD AS A RESULT OF A DISTURBANCE FROM A RECURRENT CORONAL HOLE.
