INFO FROM SIDC - RWC BELGIUM 2015 Mar 03 12:17:11

 

NOAA 2290, now well behind the NW solar limb, was the only region actively flaring. It produced 3 M-class flares peaking resp. at 15:28UT (M3.7), 19:31UT (M4.1) and 01:35UT (M8.2). Proton flux remained at nominal levels. Current imagery seems to indicate that none of the CMEs associated to these flares had an Earth directed component. NOAA 2292 has developed a small delta structure in its middle portion, but remained quiet. 

C-class flaring is expected, with a small chance on an M-class flare.

Geomagnetic conditions ranged from quiet to active, as Earth is under the waning influence of the high speed stream from the southern polar CH. Solar wind speed gradually decreased from its maximum values near 700 km/s to its current 500 km/s. IMF was directed towards the Sun, with Bz oscillating between mostly -5 and +4 nT. A positive CH is about to transit the CM and may be of geomagnetic influence around 7 March. The geomagnetic field is expected to be quiet to unsettled, with a chance on an active episode.
