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.

SOLAR ACTIVITY SHOULD CONTINUE AT A
VERY LOW LEVEL FOR THE NEXT THREE DAYS.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. RECENT SOLAR WIND DATA
INDICATE THAT THE EXPECTED CORONAL HOLE RELATED STREAM HAS NOT YET
REACHED EARTH.
