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 IS EXPECTED TO BE LOW.
C-CLASS FARES ARE POSSIBLE FROM SEVERAL DIFFERENT AREAS, INCLUDING
9062, 9068, AND 9070.
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BECOME UNSETTLED TO ACTIVE DUE TO CORONAL HOLE EFFECTS.
