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 167 Issued at 2200Z on 16 Jun 2010IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next 3 days (17-19 June).
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic field was unsettled to active at mid latitudes. Storm
conditions occurred at high latitude stations. Elevated solar wind
speeds near 550 km/s were observed throughout the day.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly unsettled to active on day 1 (17 June) due to
coronal hole effects. Conditions are expected to be quiet to
unsettled with the chance for an isolated active period on day 2 (18
June). Mostly quiet conditions are expected on day 3 (19 June).
