The Sun Online and solar activity. January 27, 2014

2 M-flares and 5 C-class flares were observed over the last 24 hours. The bulk of the flares, including the 2 M1-flares peaking resp. at 01:22UT and 02:11UT, originated from a region behind the southeast limb. The strongest C-class flare was a C6 that peaked at 08:23UT in a group just behind the northeast limb. Both regions are the return of the old regions NOAA 1944/1946. In particular NOAA 1944 was very active at that time with numerous M- and 1 X-class flare. Both regions remained very active during
their backside transit. The two sunspot regions that are currently dominating the solar disk, NOAA 1959 and 1960, have been quiet. 
Further C-class flaring is expected with a chance on more M-class flaring. None of the observed CMEs are Earth directed. They are backside events, including an impressive CME first seen by STEREO-B/EUVI-COR2 imagery at 22:40UT. Solar wind speed was around 360 km/s, and Bz varied between -4 and +4nT. Geomagnetic conditions were quiet. Quiet to unsettled geomagnetic conditions are expected over the next 3 days.

From the Northern to the Southern Cross

Explanation: There is a road that connects the Northern to the Southern Cross but you have to be at the right place and time to see it. The road, as pictured above, is actually the central band of our Milky Way Galaxy; the right place, in this case, is dark Laguna Cejar in Salar de Atacama of Northern Chile; and the right time was in early October, just after sunset. Many sky wonders were captured then, including the bright Moon, inside theMilky Way arch; Venus, just above the Moon; Saturn and Mercury, just below the Moon; the Large and Small Magellanic Clouds satellite galaxies, on the far left; red airglow near the horizon on the image left; and the lights of small towns at several locations across the horizon. One might guess that composing this 30-image panorama would have been a serene experience, but for that one would have required earplugs to ignore the continuedbrays of wild donkeys.

The Rosette Nebula (also known as Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in theMonoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the starsof the cluster having been formed from the nebula’s matter. The cluster of stars is visible in binoculars and quite well seen in small telescopes while the nebula itself is more difficult to spot visually and requires a telescope with a low magnification.

Silvery River


Peoples in Eastern Asia believed that the hazy band of stars was the “Silvery River” of Heaven (Chinese: 銀河, Korean: eunha and Japanese: ginga). In one story, the stars Altair and Vega were said to be two lovers who were allowed to meet only once a year on the seventh day of the seventh month, when a flock of magpies and crows formed a bridge over the galactic river. That day is celebrated as Qi Xi, the Seventh Night (Chinese: 七夕, Korean: chilseok and Japanese: tanabata).
