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 159 Issued at 2200Z on 08 Jun 2010

IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z

Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very low with a slight chance for a C-class event for the next 3 days (9-11 June).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was mostly quiet with the exception of an isolated unsettled period between 1500-1800Z. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be mostly quiet to unsettled with an isolated period of active conditions likely early on day 1 (9 June). Conditions are forecast to be quiet on days 2 and 3 (10-11 June).
