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 180 Issued at 2200Z on 29 Jun 2017

IA. 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 1 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
The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 466 km/s at 29/0145Z. Total IMF reached 6 nT at 29/0642Z. The maximum southward component of Bz reached -5 nT at 29/0728Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 548 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on days one and two (30 Jun, 01 Jul) and quiet to active levels on day three (02 Jul).
