Bulletin

Solar activity remains to be very low without any flares reported during last 24 hours. The only active region observed on the visible side of the Sun, NOAA AR 2694 is decaying and it has presently alpha configuration of its photospheric magnetic field. We expect that this very low solar activity will persist in the coming hours. There were no Earth directed CMEs observed during last 24 hours, and the solar protons are at background level. Solar wind speed is slowly decreasing and it is presently about 470 km/s. The interplanetary magnetic field magnitude is stable having the value of 3 nT. The fast solar wind associated with the coronal hole (between N05 and N30) which reached central meridian yesterday morning might be expected at the Earth late on January 12. The geomagnetic conditions are quiet and we expect them to stay so in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 023, gebaseerd op 05 stations.
