The Sun Online and solar activity. December 9, 2013

Flaring activity is at the same level as the previous days: the base X-ray radiation curve is situated near the bottom of the C-level. The active region which is contributed the highest probability to flare is NOAA AR1917. The region in the northern hemisphere which rotates over the east limb (but has no NOAA NR yet) is also in the running to produce C-flares.
The shock arrival of yesterday December 8 didn’t cause any geomagnetic disturbance. The co-rotating interaction region (arrival on December 7) and the associated fast solar wind dominated the solar wind data. The result was a geomagnetic storm of Kp=6 early December 8.
The mass ejection that was associated with the M1.2 flare peaking at 7:29UT on December 7 might cause a glancing blow late today (December 9) or tomorrow (December 10).

Comet Lovejoy Over a Windmill

Lovejoy continues to be an impressive camera comet. Pictured above, Comet C/2013 R1 (Lovejoy) was imaged above the windmill in Saint-Michel-l’Observatoire in southern France with a six-second exposure. In the foreground is a field of lavender. Comet Lovejoy should remain available for photo opportunities for northern observers during much of December and during much of the night, although it will be fading as the month progresses and highest in the sky before sunrise. In person, the comet will be best viewed with binoculars. A giant dirty snowball, Comet Lovejoy last visited the inner Solar System about 7,000 years ago, around the time that humans developed the wheel.

M 20: The Trifid Nebula

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764. Its name means ‘divided into three lobes’. The object is an unusual combination of an open cluster of stars; anemission 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 trifid 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.
