INFO FROM SIDC - RWC BELGIUM 2015 Mar 05 12:21:40

 

The strongest event of the period was a C3.5 flare peaking at 09:47UT by the active region at or just behind the southeast limb. Two C1 flares were observed, with sources resp. NOAA 2293 and a spotless region currently located at S10E40. Both eruptions showed interaction with a nearby filament. If the filament near NOAA 2293 erupts, it may be geo-effective. No earth-directed coronal mass ejections were observed.

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

Quiet to unsettled geomagnetic conditions were observed, with locally (Dourbes) an active episode at the beginning of the period. Solar wind speed varied mostly between 530 and its current 440 km/s, with Bz mostly positive and varying between -5 and +6 nT. The interplanetary magnetic field was mostly directed away from the Sun.

Quiet to unsettled geomagnetic conditions are expected, until the arrival of the high speed stream from a coronal hole late on 06 or on 07 March when active episodes may be possible.
