The Sun Online and solar activity. March 17, 2014

CACTus sent out an automated alert about a partial halo CME on March 16, coming into the FOV of SOHO/LASCO at 03:24UT. The tool considered two CME’s as one, resulting in a too big angular CME width.
From 02:00UT, a filament in the SE started to rise and finally erupted. The CME coming into the LASCO FOV at 03:24UT (with an angular width of around 90 degrees) is probably linked with this filament eruption and propagates well below the ecliptic plane towards the SE.  No impact on the Earth is expected.

Warped Sky: Star Trails over Arches National Park

What’s happened to the sky? A time warp, of sorts, and a digital space warp too. The time warp occurs because this image captured in a single frame a two and a half hour exposure of the night sky. As a result, prominent star trails are visible. The space warp occurs because the picture is actually a full 360 degree panorama, horizontally compressed to fit your browser. As the Earth rotated, stars appeared to circle both the North Celestial Pole, on the left, and the South Celestial Pole, just below the horizon on the right. The above panorama over Arches National Park in Utah, USA, was captured two weeks ago during early morning hours. While the eye-catching texture of ancient layered sandstone covers the image foreground, twenty-meter tall Delicate Arch is visible on the far right, and the distant arch of our Milky Way Galaxy is visible near the image center.

NGC 3576 is a minor nebula in the Sagittarius arm of the galaxy a few thousand light-years away from the Eta Carinae nebula. Eventually this nebula even received six different classification numbers. Currently, astronomers call the entire nebula NGC 3576. A popular nickname is “The Statue of Liberty Nebula” because of the distinctive shape in the middle of the nebula.
