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 307 Issued at 2200Z on 02 Nov 2012

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

Solar activity was very low. Todays activity consisted of a few, low-level B-class flares. All the regions on the disk were quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to be very low for the next three days with just a chance for an isolated C-class event.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was mostly quiet during the past 24 hours. The interplanetary magnetic field (IMF) steadily weakened throughout the period from initial values around 10 nT to day-end values around 3 nT. The z-component of the IMF (Bz) turned northwards at about 0300Z and solar wind velocity was at nominal values between 300 to 320 km/s.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be predominantly quiet for the next three days (03-05 Nov).
