# SIDC Weekly bulletin on Solar and Geomagnetic activity #
#--------------------------------------------------------------------#
WEEK 510 from 2010 Oct 04
SOLAR ACTIVITY
-------------------------
Flaring activity was low during the past week. There were quite a lot of B-flares, but the only flare of C-level this week occurred on Monday Oct. 4 around 16h35. It was a C2.3 flare originating form NOAA AR 1109, which was already turning over the west limb at that time. A first filament eruption was observed on Oct. 6 around 2h08. Linked to this event, there was a long duration B-flare and a slow CME (seen in STEREO/A COR2 around 6h54 UT). Another filament eruption occurred on the morning of Oct. 7 and was observed heading north in STEREO and LASCO data. On Oct. 8 there was a back-sided CME observed in STEREO/A images.
GEOMAGNETIC ACTIVITY
-------------------------------------
Geomagnetic conditions were quiet during the past week. Kp reached a maximum level of 3.
