The Sun Online and solar activity. January 13, 2014

There are currently eight numbered sunspot groups on the solar disc, and the most complex one is the Catania sunspot group 98 (NOAA AR 1944). The flaring activity, during last 24 hours, was at the B-class level. The last C-class flare reported was C3.9 flare which peaked at 02:06 UT, on January
12. The flare originated from the Catania sunspot group 98 (NOAA AR 1944) which continues to decay, but remains classified as a beta-gamma sunspot group. We expect C-class flares and possibly but not very probably M-class flare. Catania sunspot group 98 (NOAA AR 1944) is at the moment close to
the west solar limb, therefore, we maintain the warning condition for a proton event. The Earth is currently inside a fast solar wind (800 km/s), associated with the extended (in latitude and in longitude) coronal hole in the northern hemisphere which first reached the central meridian on January 8. The interplanetary magnetic field magnitude is about 7 nT. We expect quiet to unsettled geomagnetic conditions in the next 24 hours.

A Trip to the Moon


Image Credit: Georges Méliès, Wikipedia What would it be like to visit the Moon? The first major fictional cinematic film exploring this enduring transcultural fantasy was titled Le voyage dans la lune (A Trip to the Moon) and made in 1902, becoming one of the most popular movies of the early years of the twentieth century. The silent film starred the filmmaker Georges Melies himself and portrayed a club of astronomers voyaging to the Moon and back. Pictured aboveis a frame from the movie that has become an enduring icon for both film and space. Alluding to a bullseye trajectory, the Man in the Moon is caricatured as being struck by the human-built spaceship. The entire 14-minute film is now freely available. Visiting the Moon remained a very popular topic even 67 years later in 1969 when humans first made an actual voyage.

IC 2177: Seagull Nebula


IC 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. It is a roughly circular HII region centered on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as, “pretty bright, extremely large, irregularly round, very diffuse.”

The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighboring regions of star clusters, dust clouds and reflection nebulae. This latter region includes the open clusters NGC 2335 and NGC 2343.
