Bulletin

A new beta region has emerged near disc centre. There were no flares on the visible solar disc of the Sun in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 10%.

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.

In the past 24 hours, solar wind speed near Earth as registered by DSCOVR varied between about 365 and 460 km/s, with current values around 405 km/s. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 0 and 6 nT. Bz was never below -5 nT.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 1) were registered in the past 24 hours. Quiet to unsettled conditions (K Dourbes < 4) are expected on November 15, 16 and 17.

Today's estimated international sunspot number (ISN): 014, based on 18 stations.
