Bulletin
NOAA AR 2017 produced two M class flares (M2.0 peak 19:18 UT and M2.6 peak 23:51 UT on March 28). The flares were associated with two halo CMEs, the first one with speeds of 412km/s (first seen by LASCO-C2 at 20:00 UT) and the second one 557 km/s (at 23:58 UT). The combination of these CMEs may arrive to the Earth and cause up to minor storm conditions by 1 April around 05:00 UT. Geomagnetic conditions are quiet to unsettled, no disturbances are expected in the next 48h.
