INFO FROM SIDC – RWC BELGIUM 2014 Nov 25 12:24:52

Three C-class flares were observed, all originating from NOAA 2217. The
strongest was a C2.8 flare peaking at 18:09UT (24 November). The other five
sunspot regions were quiet. No Earth directed CMEs were observed.

More C-class flares are expected, with a small chance on an isolated
M-class flare.

Solar wind was at nominal values, with wind speed mostly between 350 and
400 km/s, and Bz between -6 and +4 nT. The IMF is directed away from the
Sun. The geomagnetic field was quiet to unsettled (K<4), and is expected to
remain so.

Andromeda Galaxy

26 ноября

 

The Andromeda Galaxy /ænˈdrɒmɨdə/ is a spiral galaxy approximately 2.5 million light-years (2.4×1019 km) from Earth[4] in theAndromeda 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 princessAndromeda. 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.
