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 04-2100Z to 05-2100Z
Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (06 Oct,
07 Oct, 08 Oct).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 575 km/s at 04/2119Z. Total IMF reached 5
nT at 04/2106Z. The maximum southward component of Bz reached -5 nT at
04/2114Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 6832 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (06 Oct) and quiet levels
on days two and three (07 Oct, 08 Oct).
