Report of Solar Geophysical Activity

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 183 Issued at 2200Z on 02 Jul 2015

IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
02/1530Z from Region 2376 (N13E32). There are currently 5 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 (03
Jul, 04 Jul, 05 Jul).

IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z: 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 426 km/s at
02/0032Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 5 pfu at 02/0030Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 5446 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (03 Jul), quiet to unsettled levels on
day two (04 Jul) and unsettled to minor storm levels on day three (05
Jul).
