Sun online and solar activity 27.11.2014


INFO FROM SIDC – RWC BELGIUM 2014 Nov 27 12:54:59 NOAA 2222 developed close to the southeast limb and is actively flaring. It was responsible for at least 10 C-class flares, including a C8.2 flare peaking at 00:47UT which was the strongest event of the observing period. Departing region NOAA 2209 was the only other region to produce a C-class flare. The other regions were quiet, with NOAA 2219 having some mixed polarities. The x-ray background flux increased from about B9 to nearly C2. A filament eruption was observed in the NW quadrant around 16:00UT on 26 November. A slow CME first observed in LASCO/C2 at 17:36 may have been associated to it. The other filaments were quiet. None of the observed CMEs are directed to Earth. Low-level M-class flares are possible. A sector boundary crossing (SBC) occurred around 03:00UT. IMF turned towards the Sun. Solar wind speed gradually increased from about 300 to 400 km/s. Bz varied between -7 and +9 nT, but was mostly positive after the SBC. The geomagnetic field was quiet. Geomagnetic conditions are expected to be quiet to unsettled, with an isolated active period not excluded.

Triangulum Galaxy



28 ноября


The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares withMessier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way, theAndromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with thenaked eye.
