Only B-class flares were observed during the last 24 hours. The strongest was a B7.2 flare peaking at 06:56UT (29 May) and produced by NOAA 2548. A long-duration B3.4 event (peaking at 03:21UT) had the spotless active region near the northeast limb as its source. The associated coronal mass ejection had no earth-directed component. Small region NOAA 2549 was stable and produced a B2 flare. No earth-directed coronal mass ejections (CMEs) were observed.

There remains a chance on an isolated C-class flare.

Earth remained under the weakening influence of a coronal hole (CH) high speed stream (HSS). Solar wind speed decreased from an initial range between 450 and 550 km/s to values between 400 and 450 km/s at the end of the observing period. Bz varied mostly between -6 and +6 nT. The interplanetary magnetic field was directed towards the Sun. Quiet to unsettled geomagnetic conditions were observed, with Dourbes recording an active episode during the 21UT-interval.

Quiet to active geomagnetic conditions are expected with the arrival of the HSS from the northern CH later today or tomorrow. There's a small chance on an isolated minor storming episode.
