Bülletään

NOAA 2381 still has some mixed magnetic polarities. It was responsible for most of the flaring activity, including the strongest flare of the past 24 hours (M1.7 peaking at 20:40UT). No Earth-directed coronal mass ejections (CME) have been observed. The other sunspot regions are small and quiet. A strong CME, first observed by LASCO/C2 at 15:12UT near the southeast limb, was related to a backside event. The probable source region is at or just behind the southeast limb.

C-class flares are expected, with a good chance on an isolated M-class flare.

Earth is gradually exiting the high speed, low density stream of the negative coronal hole (CH). Solar wind speed varied mostly between 450 and 500 km/s, with Bz varying between -4 and +5 nT. A positive equatorial CH is transiting the central meridian.

Quiet to unsettled geomagnetic conditions are expected, with an active episode not excluded.
