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 152 Issued at 2200Z on 01 Jun 2015IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z
Solar activity has been at very low levels for the past 24
hours. There are currently 3 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 (02 Jun,
03 Jun, 04 Jun).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
398 km/s at 31/2153Z. Total IMF reached 8 nT at 31/2240Z. The maximum
southward component of Bz reached -6 nT at 31/2231Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (02 Jun, 03 Jun, 04
Jun).
