FAST WARNING ‘PRESTO’ MESSAGE from the SIDC (RWC-Belgium) 2014 Nov 30 18:52:51 The Presto alert message concerning the partial halo CME, first visible in LASCO/C2 on 28 November at 22:12UT, as reported by CACTus, is erroneous. This 220 degrees wide halo, stretching from the east side of the Sun over north to the west, is actually the result of a complex series of separate CMEs that occurred between noon on 28 November and the morning of 29 November. Most notable were a filament eruption west of the central meridian (afternoon of 28 November) and a prominence eruption at the northeast limb on 29 November around 02:00UT. At least 2 other CMEs were involved, but their source is uncertain. None of these CMEs had an Earth directed component.

The Andromeda Galaxy /ænˈdrɒmɨdə/ is a spiral galaxy approximately 2.5 million light-years (2.4×1019 km) from Earth[4] in the Andromeda constellation. Also known as Messier 31, M31, or NGC 224, it is often referred to as the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the nearest galaxy overall. It gets its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princess Andromeda. The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies.
