Bulletin

Solar activity remains very low, no C-class flares in past 24h. A new active region rotating over the east limb may create C-class flares in the coming hours. The Earth is still inside the (vanishing) influence of the fast speed stream from an equatorial coronal hole. Geomagnetic conditions have decayed to active levels. They may increase again as the fast solar wind stream from a northern latitude coronal hole may arrive to the Earth within 48h. The CME from October 7 has low chances of hitting the Earth in 24h.

Today's estimated international sunspot number (ISN): 024, based on 19 stations.
