Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 261 Issued at 2200Z on 17 Sep 2012
IA. Analysis of Solar Active Regions and Activity from 16/2100Z
to 17/2100Z: Solar activity has been at low levels for the past 24
hours. Two low level C-class solar events were observed today from
around the southeast limb, from a yet to be numbered active region.
The remaining 5 sunspot regions, currently on the visible disk, have
remained stable and quiet. Three CMEs were observed in the past 24
hours, however none of them appear to be Earth-directed.
IB. Solar Activity Forecast: Solar activity is expected to be at
low levels with a slight chance for M-class events for the next
three days (18-20 September).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z:
The geomagnetic field has been at predominantly quiet levels for the
past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at mostly quiet levels on days one and two (18-19
September). Quiet to unsettled levels are expected on day three (20
September) as a coronal hole high speed solar wind stream is
forecast to become geoeffective.
