Bülletään

There are no active regions on the visible solar disk, no C-class flares in past 24 h (only minor B-class flaring). Solar activity has been very low and is expected to remain so, although a region rotating into view from the east limb may increase activity slightly in the coming hours.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 550 km/s with interplanetary magnetic fields of 10 nT. Geomagnetic conditions reached active values locally (k=4 at Dourbes) and minor storm levels planetary (Kp=5), from 21:00 UT until midnight, as a consequence of the arrival of the high speed stream from a negative polarity coronal hole (with speeds reaching 550 km/s and magnetic fields up to 20 nT). Disturbed geomagnetic conditions are expected for the next 48 hours (up to minor storm levels).
