The Sun Online and solar activity. February 16, 2014

The strongest flare in past 24 hours was M1.1 flare peaking at 09:26 UT on February 16. The flare originated from the Catania sunspot group 44 (NOAA AR 1977) which currently has beta-gamma configuration of its photospheric magnetic field. No Earth-directed CMEs were observed during last 24 hours. We expect C-class flares and possibly also M-class flares.  The Catania sunspot group 36 (NOAA AR 1974) still has beta-gamma-delta configuration of its photospheric magnetic field and it is situated close to the West solar limb so we maintain the warning condition for a proton event.The solar wind speed is currently 370 km/s and slowly decreasing. The interplanetary field magnitude is elevated (about 18 nT) due to arrival of the shock wave on February 15, at about 12:35 UT, associated with multiple ICME. The Bz component of the interplanetary magnetic field is at the moment positive. A few intervals of negative Bz occurred since the arrival of the shock wave, and the longest one was around midnight of February 16 which resulted in geomagnetic disturbance (Kp=5, as reported by NOAA and K=5 as recorded by Izmiran). The fast flow, associated with the low-latitude coronal hole in the northern hemisphere (between N20 and N40)
which reached the central meridian on February 13 is expected at the Earth later today or early tomorrow. We expect active to minor storm geomagnetic conditions to continue due to the expected arrival of CMEs observed on February 12 and February 13.

Inside the Eagle Nebula

From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. In this cavity tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and dust. The Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of the Serpent (Serpens). This picture combines three specific emitted colors and was taken with the 0.9-meter telescope on Kitt Peak, Arizona,USA.

Star forming region NGC 2264: The Cone Nebula and the Christmas Tree Cluster

The Cone Nebula is an H II region in the constellation of Monoceros. It was discovered by William Herschel on December 26, 1785, at which time he designated it H V.27. The nebula is located about 830 parsecs or 2,700 light-years away from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC 2264 in the New General Catalogue refers to both objects and not the nebula alone. The diffuse Cone Nebula, so named because of its apparent shape, lies in the southern part of NGC 2264, the northern part being the magnitude-3.9 Christmas Tree Cluster. It is in the northern part of Monoceros, just north of the midpoint of a line from Procyon to Betelgeuse.
