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 174 Issued at 2200Z on 23 Jun 2009IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity was very low. No flares occurred during
the past 24 hours. Region 1023 (S25E15) was the only spotted group
on the disk and was stable and quiet.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (24-26 June).
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet with a chance for unsettled levels for
the first day (24 June) due to possible coronal hole effects.
Activity levels are expected to be quiet for the second and third
days (25-26 June).
