Bulletin

The Sun is spotless and did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at only 1%.

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 Interplanetary Magnetic Field (IMF) near Earth registered by ACE changed orientation from away from the Sun to towards the Sun at 23:23 UT on December 31, and its magnitude varied between about 0 and 8 nT. Solar wind increased from about 290 to about 330 km/s after 23:23 UT. Bz was never below -5 nT. Quiet to mildly enhanced solar wind conditions are expected in the next 24 hours.

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 geomagnetic levels (K Dourbes < 4) are expected on January 1, 2 and 3, with a slight chance for active intervals (K Dourbes = 4) on January 1 and 2, due to the influence of a weak solar wind stream associated with a negative polarity coronal hole.

Today's estimated international sunspot number (ISN): 007, based on 13 stations.
