Two M-Class Flares / Sunspot 1476
Solar activity increased to moderate levels thanks to newly numbered Sunspot 1476. This new region rotated into view off the northeast limb and has so far produced a pair of M-Class flares. The latest event was an M1.3 at 23:01 UTC Saturday evening. solar activity is again increasing.

Solar Update
Solar activity increased somewhat due to the new sunspot rotating into view off the northeast limb. This region should be numbered 1476 on Saturday. There will be a chance for an M-Class event. All other regions have been fairly quiet with the exception of a C2.0 flare around Sunspot 1471 in the southern hemisphere.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 126 Issued at 2200Z on 05 May 2012
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity was at moderate levels. New Region 1476
(N09E67) produced several C-class flares along with an M1/Sn at
05/1329Z. The regions proximity to the limb makes spot
classification difficult, however, it is currently considered a
Dko-beta type group. Region 1469 (S26W77) continues to produce low
level C-class activity as it rotates around the west limb. A model
run was completed after the forecast was issued yesterday to include
the CME observed off the southwest limb yesterday. It was determined
that the CME has a slight Earth-directed component. A second CME,
first visible in STEREO A COR2 imagery at 05/0309Z, appeared to be
associated with a C1 flare from Region 1469 observed at 04/2350Z.
Although both CMEs have a weak Earth-directed component, neither are
expected to cause significant geomagnetic activity. A third CME
associated with a C2/Sf flare from Region 1470 (S15W31) observed at
05/0639Z, first became visible in SDO AIA imagery at approximately
05/0600Z. Due to the source location, it is probable that the CME is
Earth-directed and a model run is currently in progress to determine
geoeffectiveness.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a chance for M-class flares for the next three days (06-08
May).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on day one (06 May). Quiet to unsettled
conditions are possible on days two and three (07-08 May) due to
weak effects from the CMEs observed on 04 May.
