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 173 Issued at 2200Z on 22 Jun 2001

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

Solar activity was low. The largest event was a C6/Sn event at 22/1828 UTC from Region 9511 (N10E25). Regions 9503 (N17W46). 9504 (N09W42), and 9509 (S09W45) all produced minor activity during the period. The rest of the sun was mostly quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to be at mostly low to moderate levels. Isolated M-class flares are possible during the period.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was at quiet to unsettled conditions. The greater than 2 MeV electron flux reached high levels during the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to remain at quiet to unsettled levels. The greater than 2 MeV electron flux may again reach high levels during the first half of the forecast period and then is expected to return to moderate to normal levels.
