Catania sunspot group 78 (NOAA AR 1665) and 79 (NOAA AR 1667) produced several C-flares since yesterday. The probability for more C-flares is slightly above 50%. The geomagnetic conditions were unsettled. This was probably caused by the small equatorial coronal hole. Another coronal hole in the northern hemisphere at high latitude can cause again unsettled conditions from tomorrow, Feb 4 onwards.
