Solar activity was low during the past 24 hours. There was only one C2.8-class flare originating from a new active region NOAA AR 1760, which just rotated behind the east limb. Catania regions 82 and 83 (resp NOAA AR 1756 and 1755) have a simple magnetic beta configuration and are further decreasing in size. No Earth directed CMEs are detected. C-class flaring conditions are expected for the next 48 hours, mainly originating from NOAA AR 1760. The solar wind further slowed down to a speed of 400 km/s. The interplanetary magnetic field is stable with a magnitude of less than 5 nT. Geomagnetic conditions are quiet (local K<3 at Dourbes). This situation is expected to remain so for the next few hours till the arrival of the fast flow from the coronal hole in the centre of the solar disk. This might result in geomagnetically active to minor storm levels (K= 4 to 5).
