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).

The strangest moon in the Solar System is bright yellow. This picture, an attempt to show how Io would appear in the “true colors” perceptible to the average human eye, was taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003. Io’s colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes. The intense tidal gravity of Jupiterstretches Io and damps wobbles caused by Jupiter’s other Galilean moons. The resulting friction greatly heats Io’s interior, causing molten rock to explode through the surface. Io’s volcanoes are so active that they are effectively turning the whole moon inside out. Some of Io’s volcanic lava is so hot it glows in the dark.

The Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga).
