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 152 Issued at 2200Z on 01 Jun 2010

IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z

Solar activity was very low. The SOHO C2 imagery observed a slow moving CME at 31/2154Z. The plane of sky speed was estimated around 307 km/s. This event was correlated with a disappearing filament located near N30W30. No flares were observed during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was at quiet to active levels. The ACE spacecraft observations show the continued presence of the coronal hole high speed stream. Solar wind speeds are around 525 km/s with IMF Bz at +/- 6 nT. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled with isolated active conditions for the next two days (02-03 June). Predominantly quiet levels are expected for day three (04 June) as the high speed stream subsides.
