The Sun Online and solar activity. March 24, 2014

Several C-class flares in past 24h. The strongest one was a C4.5 flare from AR 2014 peaking at 00:10 UT. AR 2010, 2014 and 2015 have potential for M-class flares.Geomagnetic conditions are quiet, solar wind speed is around 400 km/s with IMF values lower than 5 nT. The conditions may reach active and minor storm levels when/if the CME of March 23 arrives to the Earth, expected early on March 26.

Orion and Aurora over Iceland

If you see a sky like this – photograph it. A month ago in Iceland, an adventurous photographer (pictured) chanced across a sky full of aurora and did just that. In the foreground lies the stratovolcanoÖræfajökull. In the background, among other sky delights, lies the constellation of Orion, visible to the aurora’s left. Auroras are sparked by energetic particles from the Sun impacting the magnetic environment around the Earth. Resultant energetic particles such as electrons and protons rain down near the Earth’s poles and impact the air. The impacted air molecules obtain excited electrons, and when electrons in oxygen molecules fall back to their ground state, they emit green light. Auroras are known to have many shapes and colors.

NGC 253: Sculptor Galaxy

As one of the brightest galaxies in the sky, the Sculptor Galaxy can be seen through binoculars and is near the star Beta Ceti. It is considered one of the most easily viewed galaxies in the sky after the Andromeda Galaxy.

The Sculptor Galaxy is a good target for observation with a telescope with a 300 mm diameter or larger. In such telescopes, it appears as a galaxy with a long, oval bulge and a mottled disc. Although the bulge appears only slightly brighter than the rest of the galaxy, it is fairly extended compared to the disk. In 400 mm scopes and larger, a dark dust lane northwest of the nucleus is visible, and over a dozen faint stars can be seen superimposed on the bulge.
