Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 061 Issued at 2200Z on 01 Mar 2012
IA. Analysis of Solar Active Regions and Activity from 29/2100Z
to 01/2100Z: Solar activity has been low. There was one C-class
flare duing the past 24 hours, a C3/1f from Region 1423 (N17W21) at
01/1526Z. New Region 1427 (N15W01) was numbered today. A CME was
observed at 29/1824Z (using LASCO C2) from the north polar region of
the sun, however it is not expected to be geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 29/2100Z to 01/2100Z:
The geomagnetic field has been quiet to active with isolated storm
periods at high latitudes. The elevated activity appears to be
related to a solar sector boundary crossing.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled for the first and second days
(02-03 Mar) due to a small yet well positioned coronal hole. A
return to quiet levels is expected on the third day (04 Mar).
III. Event Probabilities 02 Mar-04 Mar
Class M 01/01/01
Class X 01/01/01

Latest Report of Solar flare and Geophysical Activity
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).
Solar Update / New Record
Solar activity continues on at very low levels.There is currently no chance for strong solar flares. A new sunspot is trying to form to the east of sunspot 1423 and is pictured below.
Despite the lack of Sunspots, February 29th will mark the 199th day in a row with an official visible Sunspot counted by SWPC Space Weather Operations (SWO). This is a new record for Cycle 24 and beats the previous record of 198 days set on August 13, 2011.
