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.

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

Solar activity was low. Region 567 (S12W16) produced two C-class flares during the past 24 hours, a C1 at 02/2149 UTC and a C1 at 02/2327 UTC. A CME was observed from the southeast limb, beginning at 02/2354 UTC, but was not earthward directed and was probably from a backside source. Region 567 is showing slow growth and may be building up some weak shear along its backward S-shaped polarity inversion line. The remainder of the disk was quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to low for the next three days (04-06 March). Region 567 is expected to produce additional C-class level activity. There is a slight chance for an isolated M-class event.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was mostly quiet to unsettled. There was an interval of active to minor storm levels between 0900-1500 UTC. The greater than 2 MeV electron fluxes were high during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled with some isolated active periods for 04 March. Mostly unsettled levels are expected for 05 March and quiet to unsettled levels are expected for 06 March. The decrease in activity is expected from the slow decline of the high speed solar wind stream.
