The solar activity remains low with only small C-class flares reported in the past 24h. These flares mostly occurred in NOAA AR 2132, which is currently the most active region on the solar disk. More flaring at C-class level is expected from NOAA AR 2132 and 2134, with a small chance for a low M-class flare. A type II radio burst was observed in Humain on August 5 at 15:50. It was related to a C1.1 flare at location N11E51, close to NOAA AR 2134 and to a narrow CME observed by LASCO at 16:24 UT towards the north-east. This CME is not earth-directed. A wide CME was observed in LASCO at 04:36 UT today after a long data gap. This CME was probably associated to an eruption in NOAA AR 2121, which has already turned over the west limb, but is visible in STEREO images around 20:00 UT on August 5. At that time SDO images also show erupting loops behind the west limb. This CME is thus back-sided and will not affect the earth. Geomagnetic conditions have been quiet to unsettled (K up to 3). We expect a return to quiet conditions. Late on August 7 and on August 8, unsettled to active conditions (K max 4) are possible due to the expected arrival of a coronal hole fast wind stream.
Today's estimated international sunspot number (ISN): 075, based on 10 stations.
