The Sun Online and solar activity. September 3, 2014

A partial halo CME was detected yesterday in association with the eruption of a long filament in the northern hemisphere. The CME first appeared in the SOHO/LASCO C2 field of view at 16:36 UT, had angular width around 190 degrees and the projected plane-of-the-sky speed around 450 km/s. Despite
the position of the CME source region not far from the solar disk center, the bulk of the CME material went northward of the ecliptic plane. The arrival of the corresponding ICME and even of the ICME-driven shock at the Earth is unlikely, so no resulting geomagnetic disturbance is expected. This CME is a far side event as seen from Venus, so it will not affect Venus either.

M6: The Butterfly Cluster 

Image Credit & Copyright: Marco Lorenzi

 To some, the outline of the open cluster of stars M6 resembles a butterfly. M6, also known as NGC 6405, spans about 20 light-years and lies about 2,000 light years distant. M6, pictured above, can best be seen in a dark sky with binoculars towards the constellation of the Scorpion (Scorpius), coving about as much of the sky as the full moon. Like other open clusters, M6 is composed predominantly of young blue stars, although the brightest star is nearly orange. M6 is estimated to be about 100 million years old. Determining the distance to clusters like M6 helps astronomers calibrate the distance scale of the universe.

Running Man Nebula, NGC 1977

The Running Man Nebula NGC 1977, located in the constellation of Orion, is so named because it looks like a man running in the midst of the cloud of gas. It is a reflection nebula that does not emit any visible light of its own.
