The Sun Online and solar activity. March 26, 2014

Only C1 flares in past 24h, from NOAA AR 2010 (lost its delta configuration, now it is beta gamma) and 2015. The warning conditions for protons is maintained, as most of the big flare-producing ARs are now
located in the western hemisphere.The shock from the CME of Mar 23 arrived at 19:25 UT on March 25. It caused active geomagnetic conditions at interplanetary (Kp = 4) and local (KDourbes = 4) indices. Quiet to
unsettled geomagnetic conditions are expected for the next 48h.

M78 and Reflecting Dust Clouds

An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Of the two reflection nebulas pictured above, the more famous nebula is M78, in the image center, while NGC 2071 can be seen to its lower left. The same type of scattering that colors the daytime sky further enhances the blue color. M78 is about five light-years across and visible through a small telescope. M78 appears above only as it was 1600 years ago, however, because that is how long it takes light to go from there to here. M78 belongs to the larger Orion Molecular Cloud Complex that contains the Great Nebula in Orion and the Horsehead Nebula.

NGC 3199 in the constellation of Carina

 NGC 3199 lies about 12,000 light-years away, a glowing cosmic cloud in the southern constellation of Carina. The nebula is about 75 light-years in diameter.  Near the center of the ring is a Wolf-Rayet star, a massive, hot, short-lived star that generates an intense stellar wind. In fact, Wolf-Rayet stars are known to create nebulae with interesting shapes as their powerful winds sweep up surrounding interstellar material.
