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 182 Issued at 2200Z on 01 Jul 2015IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 01-2100Z 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
30/2211Z from Region 2376 (N13E57). There are currently 3 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 (02
Jul, 03 Jul, 04 Jul).
IIA. Geophysical Activity Summary 30-2100Z 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
446 km/s at 01/1318Z. Total IMF reached 6 nT at 01/0624Z. The maximum
southward component of Bz reached -4 nT at 01/1336Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 3 pfu at
01/1920Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 5953 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (02 Jul, 03 Jul, 04
Jul).
