An X4.0 flare has occurred with a peak time 06:54 UTC on May 10, produced by NOAA AR 3664. Type II and type IV radio emissions were detected at 06:46 UTC and 06:51 UTC, respectively, during the flaring activity. The GOES proton flux is increasing but still remains below the 10 pfu threshold level. Moderately disturbed radio communications have been observed related to this flaring activity.

The 10 MeV GOES proton flux has crossed the 10 pfu threshold level at 13:30 UTC on May 10. It is currently above the threshold level and it is increasing. It started to increase around 11:00 UTC on May 09. Multiple coronal mass ejections and strong flaring activities from NOAA AR 3664 have large probability to be associated with this particle event. The proton flux is expected to remain elevated as more particle events are possible in the coming days.

A partial halo coronal mass ejection (CME) was observed on SOHO/LASCO-C2 images around 07:12 UTC on May 10. This CME is associated with a X4.0 flare, which peaked at 06:54 UTC, produced by NOAA AR 3664. Associated type II and type IV radio emissions were detected at 06:46 UTC and 06:51 UTC, respectively. This CME has a projected speed of about 694 km/s (as measured by the Cactus tool). The corresponding ICME is expected to impact the Earth on May 12.

A shock was detected in the solar wind data around 16:42 UTC on May 10. The interplanetary magnetic field jumped from 4 nT to 44 nT, the solar wind speed jumped from 460 km/s to 700 km/s and the solar wind density at the shock increased from 5/cm3 to 30/cm3. The shock is related to an ICME arrival associated with one of the coronal mass ejections that was detected on May 08-09. Geomagnetic conditions have reached severe storm levels globally (NOAA Kp 8-) and major storm levels locally (K_Bel 7) starting at 15:00 UT on May 10.
