INFO FROM SIDC - RWC BELGIUM 2015 Mar 06 12:20:41

The active region that is just starting to round the southeast limb was the source of 3 M-class flares during the period. The strongest event was an M3 flare peaking at 04:57UT. It was followed by an M1.5 flare peaking at 08:15UT. A partial halo coronal mass ejection (CME) with an estimated plane-of-the-sky speed of about 600 km/s was associated to the latter event. First seen by CACTus in LASCO/C2 imagery at 07:12UT, the bulk of the CME is directed away from Earth. Based on current imagery, the CME does not seem to have an earth-directed component. NOAA 2292 produced a complex C3 flare (around 17:20UT) while rounding the southwest limb. NOAA 2293 and three other puny sunspot groups were quiet. No earth-directed CMEs were observed. Proton flux was at nominal levels. M-class flaring is expected, with a good chance on an X-class event. Quiet to unsettled geomagnetic conditions were observed, with Kp reaching active levels by the end of the period. Solar wind speed varied mostly between 400 and 500 km/s, Bz varied mostly between -7 and +8 nT. The interplanetary magnetic field was mostly directed away from the Sun. Quiet to active geomagnetic conditions are expected, with the anticipated arrival of the high speed stream from a coronal hole around 07 March.
