Bulletin

Solar activity has been very low, no C-class flares in past 24h, the situation is not expected to change.

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

The Earth is still inside a high speed solar wind stream from a coronal hole. As a consequence geomagnetic conditions reached Kp=4 (planetary) and K=4 (local at Dourbes). Solar wind speed is now at 670 km/s with interplanetary magnetic fields of 5 nT. The effect of the coronal hole is expected to fade within 24h. K levels up to 4 can still be expected.

Today's estimated international sunspot number (ISN): 000, based on 08 stations.
