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.

SDF Number 181 Issued at 2200Z on 30 Jun 2014

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

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 30/0419Z from Region 2104 (S11E51). There are currently 8 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 (01 Jul, 02 Jul, 03 Jul).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
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 375 km/s at 29/2139Z. Total IMF reached 10 nT at 29/2219Z. The maximum southward component of Bz reached -8 nT at 29/2221Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on day one (01 Jul) and quiet to unsettled levels on days two and three (02 Jul, 03 Jul).
