Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 228 Issued at 2200Z on 16 Aug 2010
IA. Analysis of Solar Active Regions and Activity from 15/2100Z
to 16/2100Z: Solar activity was low. Region 1099 (N17W84) produced
several B-class flares and also a C1 flare at 16/1639Z. New region
1100 (S24E59) was numbered today and is classified as a Axx-type
group with an alpha magnetic configuration.
IB. Solar Activity Forecast: Solar activity is expected to be very
low with a chance for C-class flares.
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z:
The geomagnetic field was mostly quiet. An isolated unsettled period
was observed at 16/0600Z. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be quiet to unsettled with isolated active periods on
days one and two (17 – 18 August) in response to the CME observed on
14 August. Mostly quiet levels are expected on day three (19
