The Sun Online and solar activity. January 1, 2014

An M9.9 flare occurred today in NOAA AR 1936, peaking at 18:52 UT. Not much data is available at the moment, but in case a strong CME is associated with this event, it has the potential to be geo-effective due to the location of the source region in the western hemisphere.

A New Year’s Crescent

OLYMPUS DIGITAL CAMERA

Image Credit & Copyright: Jay Ouellet That’s not the young crescent Moon poised above the western horizon at sunset. Instead it’s Venus in a crescent phase, captured with a long telephoto lens from Quebec City, Canada, planet Earth on a chilly December 30th evening. The very bright celestial beacon is droping lower into the evening twilight every day. But it also grows larger in apparent size and becomes a steadily thinner crescent in binocular views as it heads toward an inferior conjunction, positioned between the Earth and the Sun on January 11. The next few evenings will see a young crescent Moon join the crescent Venus in the western twilight, though. Historically, the first observations of the phases of Venus were made by Galileo with his telescope in 1610, evidence consistent with the Copernican model of the Solar System, but not the Ptolemaic system.

NGC 7635: the Bubble nebula

NGC 7635 is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The “bubble” is created by the stellar windfrom a massive hot, 8.7 magnitude young central star, the 15 ± 5 M☉ SAO 20575 (BD+60 2522). The nebula is near a giantmolecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
