A small active region developed during the first hours of Jan. 09th at about 45 degrees east and 20 degrees north. It showed weak (below B level) but repeated flaring activity and it is associated with sunspots according to Uccle white light observations. Further activity increase from this active region is not excluded and therefore the all-quiet alert is suspended. Geomagnetic activity is expected to be very quiet.
