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 061 Issued at 2200Z on 01 Mar 2012

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 01-2100Z

Solar activity has been low. There was one C-class flare duing the past 24 hours, a C3/1f from Region 1423 (N17W21) at 01/1526Z. New Region 1427 (N15W01) was numbered today. A CME was observed at 29/1824Z (using LASCO C2) from the north polar region of the sun, however it is not expected to be geoeffective.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 29-2100Z to 01-2100Z
The geomagnetic field has been quiet to active with isolated storm periods at high latitudes. The elevated activity appears to be related to a solar sector boundary crossing.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled for the first and second days (02-03 Mar) due to a small yet well positioned coronal hole. A return to quiet levels is expected on the third day (04 Mar).
