During the past 24 hours an M1.0 flare erupted from Catania sunspot group 90 (NOAA AR 1760) at 20:00 UT on May 31. This was associated with type II (speed of 1393 km/s) and type IV radio bursts. No associated strong CMEs were observed at that time. CACTus detected a partial halo CME on May 31 associated with a broad filament eruption on the north (oriented from NE to SW). It involves two successive CMEs: one with signatures in LASCO at 11:48 UT and one starting at 17:24 UT. Both CMEs mainly have a North-ward oriented component and are not oriented to the Earth. C-class flaring activity is expected and there exits a slight chance for an M-class flare. Biggest candidates are Catania sunspot groups 88 and 90. A shock was observed in the solar wind speed on May 31 around 15:30 UT. The speed went up from around 350 km/s to around 650 km/s and also corresponds to a jump in the solar wind temperature and density. On June 1, the interplanetary magnetic field reached a magnitude around 20 nT with Bz component varying between -20 and +15 nT. This is related to the arrival of a corotating- interaction region (CIR) related to the coronal hole (CH). The K index has reached storm levels (K up to 6 measured at Dourbes). We expect the minor storm conditions to continu for today activity will decrease to unsettled to active conditions tomorrow.
