Bulletin

Solar activity has been moderate, many C-class flares coming mostly from NOAA AR 1875 that rotated into view over the eastern limb and has magnetic beta configuration. NOAA AR 1865 has simplified to a beta configuration but it is still producing C-class flares. AR 1861 is about to rotate over the western limb, but remains very active, it produced an M1.2 flare peaking at 15:41 UT on October 17. A faint narrow CME was associated with this flare, not expected to arrive to the Earth. Geomagnetic conditions have been quiet and are expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 116, gebaseerd op 08 stations.
