Six sunspot groups are reported by Catania today. One of them (Catania number 35, NOAA AR 1800) has beta-gamma configuration of the photospheric magnetic field. We expect flaring activity on the C-level, although the last C-class flare took place on July 21 and only B-class flares are reported during the last days. The Earth is currently inside the slow (around 350 km/s) solar wind flow with weak to average (3-4 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions in the coming hours. Tomorrow we expect the arrival of the fast flow from the equatorial coronal hole, possibly resulting in active geomagnetic conditions.
