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
predominantly low. There is a chance for an isolated C-class event
during the next three days.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next 24 hours (24 May). Mostly
unsettled conditions are expected for the second day (25 May) due to
