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 305 Issued at 2200Z on 01 Nov 2013IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M6 event observed at
01/1953Z from Region 1884 (S13W01). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (02 Nov, 03 Nov,
04 Nov).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic

as measured by the ACE spacecraft, reached a peak speed of 427 km/s at
31/2142Z. Total IMF reached 7 nT at 31/2133Z. The maximum southward
component of Bz reached -6 nT at 31/2234Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (02 Nov, 03 Nov, 04
Nov).
