Bulletin

There were no C-class flares reported during last 24 hours. The only active region observed on the visible side of the Sun during last three days, NOAA AR 2597, is now rotating across the west solar limb. Therefore, the probability for the C-class flares to occur in the coming hours is very low (about 10 percent). No Earth directed CMEs were observed in the last 24 hours. The Earth is still inside the fast solar wind with the speed of about 650 km/s. The interplanetary magnetic field magnitude is about 5 nT, and the Bz component of the interplanetary magnetic field is fluctuating with values down to -5 nT. Due to the long interval of the negative value of the Bz and the fast solar wind, disturbed geomagnetic conditions were induced in the evening of September 29 (around 18 UT) and the local station at Dourbes reported K=5, and NOAA reported Kp=5. We expect active to minor storm geomagnetic conditions in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 23 stations.
