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 76 Issued at 2200Z on 16 Mar 2016IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
16/0646Z from Region 2522 (N14W85). There are currently 4 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 (17 Mar,
18 Mar, 19 Mar).
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 595 km/s at 16/1354Z. Total IMF
reached 10 nT at 16/0122Z. The maximum southward component of Bz reached
-8 nT at 16/2017Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 3690 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (17 Mar), quiet to unsettled
levels on day two (18 Mar) and quiet levels on day three (19 Mar).
