Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 060 Issued at 2200Z on 29 Feb 2012
IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity has been very low for the past 24 hours.
A series of CMEs were observed over the west limb at 29/0125Z,
29/0924Z, and 29/1212Z. Stereo-A imagery confirm the source regions
were behind the west limb and none of these are expected to be
geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field has been mostly quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for the first day (01 Mar). A slight increase
to quiet to unsettled levels is expected on the second day (02 Mar)
due to a small coronal hole. Quiet levels are expected on the third
day (03 Mar).
