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 22 Jun 2012

IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z

Solar activity has been very low. New Region 1511 (N15W17) was numbered.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low during the period. Region 1511 is capable of isolated C-class flare production.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
Geomagnetic field activity was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period.
IIB. Geophysical Activity Forecast
Geomagnetic activity is expected to be mostly quiet for the next three days (23 - 25 June).
