The active region that is still in the process of rotating to the visible side of the Sun was source of several B-class flares during last 30 hours. The same region was this morning also the source of C 9.3 GOES flare (peaked at 10:46 UT) and M 1.1 flare (peak at 07:24 UT). We can expect more C-class flares and possibly also isolated M-class flares in the coming hours. The coronagraph observation of the CMEs possibly associated with the C-class and M-class flares are not yet available. However, as the source region is still partially on the back side of the Sun, the possibly associated CMEs will not be Earth directed. During last 24 hours proton flux levels were at background values and are expected to remain so.

The Earth is still inside the slow solar wind with the speed of about 290 km/s. The interplanetary magnetic field magnitude is rather stable and it amounts about 4 nT. The solar wind originating from the extension of the southern polar coronal hole that crossed central meridian on May 25 might be expected later today or tomorrow morning. It might be closely followed by the solar wind originating from the small and patchy equatorial coronal hole (negative polarity) that reached central meridian on the midday of May 27. On May 30 we can also expect the arrival of the CME-driven shock wave associated with rather faint CME (observed above the west solar limb early on May 26). The geomagnetic conditions are quiet and we expect quiet to possibly active geomagnetic conditions in the next 24 hours.
