NOAA AR 2615 produced a C4.0 flare after rotating over the west limb with peak at 17:15 UT on 10 December, a CME was observed in association to it (not Earth affecting). There are no ARs visible on the solar disk. Therefore solar activity is expected to remain low over the next 48 hours, with slight chances of still observing a C-class flare from NOAA AR 2615.
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. Geomagnetic conditions reached active values at planetary level (Kp=4) but only unsettled locally at Dourbes (K=3). Solar wind speed is now at 600 km/s with interplanetary magnetic fields of 4 nT. The effect of the coronal hole is expected to fade out in 24 h. Unsettled to active conditions can still be expected today and quiet conditions as of tomorrow.
