Bulletin

A new Active Region or plage is rotating around the East limb and has produced a B1.7 flare in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 3%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR varied between about 455 and 535 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed away from the Sun and its magnitude varied between about 1 and 8 nT. Bz was below -5 nT around 16-17 UT and 18-19 UT on October 10.

Unsettled to minor storm geomagnetic conditions (K Dourbes between 3 and 5; NOAA Kp between 3 and 5) were registered in the past 24 hours. K Dourbes was equal to 5 between 18h and 24h UT on October 10, coinciding with a negative excursion of Bz. Quiet to unsettled levels (K Dourbes < 4) are expected on October 11, 12 and 13, with a chance for active intervals (K Dourbes = 4) on October 11.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 11 Stationen.
