Skrót wiadomości

Only one C-class flare was reported during last 24 hours (C1.0, peaking at 22:50 UT on December 07). We expect isolated C-class flares in the coming hours. The prominence eruption observed at the East solar limb at about 14:40 UT on December 07, was associated with the B4.2 flare and CME. Almost concurrently strong flare associated with the EIT wave and the coronal dimming, was observed by STEREO A at the back side of the Sun. The events were also associated with the type II burst, signature of the coronal shock wave. The coronagraph data are currently unavailable and it is not possible to estimate speed and the width of the CMEs associated with this two events. However, since these were limb and back side events, the CMEs are not expected to arrive at the Earth.

The Earth is still inside the fast solar wind (570 km/s). The interplanetary magnetic field magnitude decreased and its current value is about 6 nT. The Bz component of the interplanetary magnetic field is fluctuating between 5 and -5 nT. The fast flow from the equatorial coronal hole (seemingly connected with the northern polar coronal hole) which has reached the central meridian late on December 06 is expected to arrive late on December 09 or early on December 10, and it might induce active geomagnetic conditions. Currently the geomagnetic conditions are quiet to unsettled, and we expect it to remain so in the coming hours.
