Bulletin

NOAA AR 2017 released an X1.0 flare with peak at 17:48 UT on March 29, associated with radio bursts, a full halo CME and an increase in GOES proton fluxes (not passing the threshold). This region is expected to produce M-class flares and probably X-class flares, it has a beta gamma delta magnetic configuration. A type II radio burst was detected at 11:52 UT, close in time of a C-class flare, this may mark the presence of another CME, but there is no data available yet. The full halo CME related to the X1.0 flare was first seen at 18:12 UT by LASCO-C2. The speeds measured are of 510 km/s (LASCO-C3), giving an expected arrival time (using DBM) to the Earth of 04:30 UT on April 2. Geomagnetic conditions are quiet, the situation may change when/if the CMEs from March 28 arrive to the Earth early on April 1 (expected 05:00 UT).

Today's estimated international sunspot number (ISN): 063, based on 17 stations.
