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 128 Issued at 2200Z on 08 May 2014IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z
Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M5 event observed at
08/1007Z from Region 2056 (N04E44). There are currently 9 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (09 May, 10 May,
11 May).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
378 km/s at 07/2137Z. Total IMF reached 12 nT at 08/0732Z. The maximum
southward component of Bz reached -11 nT at 08/0729Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (09 May, 11
May) and quiet to active levels on day two (10 May).
