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 09-2100Z to 10-2100Z

Solar activity was low. Region 500 (S09W36) produced the first C-class flare observed in the past four days, a C1/Sf at 10/2014 UTC. This region, as well as the other two spotted sunspot groups on the visible disk, remain relatively small and simple.
IB. Solar Activity Forecast
Solar activity is expected to be low. Additional small C-class flares are possible.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field ranged from unsettled to minor storm levels. The most disturbed periods were from 10/0900-1500 UTC.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be mostly active with isolated minor storm periods. A coronal hole high speed stream is expected to influence activity levels for the next few days.
