Four C-class flares were observed since our last bulletin. The largest one was a C4.5 flare at 16:57 UT on August 8 in NOAA AR 2135, that has developed into a beta-gamma region. This region, as well as NOAA AR 2132, is expected to produce more C-class flares in the coming days. There is also a small chance for an M-flare. CACTus reported on a halo CME observed in LASCO images on August 8 around 16:36 UT. This full halo CME was associated to a strong eruption observed in the center of the solar disk in STEREO-a/EUVI 195 images starting at 15:55 UT. This is thus a back- sided event and therefore the CME will not be geo-effective. We expect quiet geomagnetic conditions to persist, with a chance for unsettled conditions (K maximum 3) under the possible influence of a coronal hole wind stream.
