The Sun Online and solar activity. March 05, 2014

There are currently 12 sunspot regions on the visible solar disk, with small delta’s observed in the trailing portion of NOAA 1991. It was also here that the strongest event of the past 24 hours took place: an impulsive M1-flare peaking at 02:10UT. Two C-flares were produced by NOAA 1986 from behind the west limb, while three C-flares took place in NOAA 1991.  Several CMEs were observed. The ones having a (partial) halo, which were first visible in LASCO/C2 at resp. 18:48UT and 21:17UT on 4 March, and
09:24UT on 5 March, were all backside events. None of the observed CMEs has an Earth-directed component, including the CME associated to a filament eruption near the northeast limb (+/- 21:00UT on 4 March).
Eruptive flaring conditions are expected, with a small chance for an M-class flare from NOAA 1991.
Solar wind speed has gradually increased to values between 400-450 km/s, with Bz varying between -5nT and +5nT. A coronal hole on the northern hemisphere has reached the central meridian and might produce active geomagnetic conditions from 8 March onwards.
Geomagnetic conditions have been quiet and are expected to remain so.

Globules in the Running Chicken Nebula

Image Credit & Copyright: Fred Vanderhaven

The eggs from this chicken may form into stars. The above pictured emission nebula, cataloged as IC 2944, is called the Running Chicken Nebula for the shape of its greater appearance. The image was taken recently from Siding Spring Observatory in Australia and presented in scientifically assigned colors. Seen near the center of the image are small, dark molecular clouds rich in obscuring cosmic dust. Called Thackeray’s Globules for their discoverer, these “eggs” are potential sites for the gravitational condensation of new stars, although their fates are uncertain as they are also being rapidly eroded away by the intense radiation from nearby young stars. Together with patchy glowing gas and complex regions of reflecting dust, these massive and energetic stars form the open cluster Collinder 249. This gorgeous skyscape spans about 70 light-years at the nebula’s estimated 6,000 light-year distance.

NGC 6334 (also known as the Cat’s Paw NebulaBear Claw Nebula) is an emission nebula located in the constellation Scorpius. It was discovered by astronomer John Herschel in 1837, who observed it from the Cape of Good Hope in South Africa.
NGC 6357, is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding “cocoons”.
