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 069 Issued at 2200Z on 10 Mar 2001IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was high. Region 9368 (N24W59) produced
an M6/1b flare at 10/0405Z, with moderate radio bursts and a Type II
sweep. A CME was also observed from this event. This moderately
complex region also produced a C9/1n flare at 09/2324Z. Region 9273
(S36W64) continues to develop and produced several minor C-class
flares throughout the period. A C6 event was observed at 10/1622Z
and was likely associated with a CME observed off the SE limb. New
Regions 9374 (S19E50) and 9375 (S16W46) were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Continued C-class and isolated M-class activity is
expected from Regions 9368, 9372, and 9370 (N10W38).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was mostly quiet with an isolated period of
unsettled conditions between 10/0300 - 0600Z. The greater than 2 MeV
electrons continue at moderately enhanced levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at mostly quiet to unsettled levels. Isolated,
high latitude active periods are possible throughout the three day
period.
