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 181 Issued at 2200Z on 29 Jun 2016IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (30
Jun, 01 Jul, 02 Jul).
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z

peak level of 2248 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (30 Jun), quiet to unsettled
levels on day two (01 Jul) and unsettled to minor storm levels on day
three (02 Jul).
