Bulletin

Beta region NOAA 2726 has emerged on November 11 but is disintegrating fast. 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 only 2%.

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.

The Earth is currently under the influence of a high speed stream associated with a negative equatorial coronal hole. Solar wind speed near Earth as registered by DSCOVR varied between about 520 and 640 km/s in the past 24 hours, with current values around 550 km/s. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 0 and 7 nT. Bz was never below -6 nT. Solar wind speed is expected to decrease over the next days.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to active geomagnetic levels (K Dourbes < 5) are expected on November 12, with a slight chance for minor storm intervals (K Dourbes = 5). Quiet to unsettled conditions are expected on November 13 and 14.

Today's estimated international sunspot number (ISN): 014, based on 07 stations.
