The Sun Online and solar activity. July 14, 2014

Catania AR 9 (NOAA 2109) produced the strongest flare of the past 24 hours,  class C1.3 peaking at 20:52 UTC on July 13. This region and NOAA 2108 will most likely produce more C-class and probably (but less likely) M-class flares as they rotate over the west limb. Geomagnetic conditions are quiet
and expected to remain so.

Auroras over Northern Canada 

Image Credit & Copyright: Kwon, O Chul (TWAN)

 Gusting solar winds and blasts of charged particles from the Sun resulted in several rewarding nights last December for those anticipating auroras. The above image captured dramatic auroras stretching across a sky near the town of Yellowknife in northern Canada. The auroras were so bright that they not only inspired awe, but were easily visible on an image exposure of only 1.3 seconds. A video taken concurrently shows the dancing sky lights evolving in real time as tourists, many there just to see auroras, respond with cheers. The conical dwellings on the image right are teepees, while far in the background, near the image center, is theconstellation of Orion.

Trifid Nebula

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent ‘gaps’ within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.
