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 157 Issued at 2200Z on 06 Jun 2015IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
06/0712Z from Region 2361 (N16E36). There are currently 8 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (07
Jun, 08 Jun, 09 Jun).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 412 km/s at
06/1800Z. Total IMF reached 8 nT at 06/1032Z. The maximum southward
component of Bz reached -7 nT at 06/0959Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (07 Jun), quiet to active
levels on day two (08 Jun) and unsettled to minor storm levels on day
three (09 Jun).
