Bulletin

The Sun did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 5%. No Earth- directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Solar wind speed measured by DSCOVR decreased from about 575 to about 530 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed away from the Sun and its magnitude ranged between about 1 and 6 nT. Quiet to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 1 and 5) were registered in the past 24 hours. Active levels (K Dourbes = 4) are possible on October 16, 17 and 18 due to continued influence of the high speed stream associated with a positive coronal hole, with a slight chance for minor storm conditions (K Dourbes = 5).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 19 stations.
