Bülletään

The active region that rotated over the east limb (NOAA AR 2651) has a beta-gamma magnetic field configuration and produced a C5.5 flare with peak at 20:10 UT on April 18. More C-class flares, and possibly M-class flares, can be expected.

A partial halo CME was associated with the C5.5 flare, first seen at 19:48 UT by LASCO-C2, directed towards the east with speeds around 900 km/s. Due to the location of the source region, only a shock could be expected to arrive at the Earth on April 21. Solar protons have remained at background levels over the past 24 hours.

The solar wind at the Earth is showing signs of compression preceding the expected high speed stream, with KDourbes reaching only 3 but Kp going to 5. Active to minor storm conditions expected.
