The Sun Online and solar activity. June 18, 2014

A partial halo CME first visible in the SOHO/LASCO C2 field of view at 09:12 UT on June 17 is related to a far side eruption in the former NOAA AR 2080 situated around S10W210, with the associated flare peaking at 08:45 UT (the last frame before a data gap) according to the STEREO A EUVI data. The CME will therefore not arrive at the Earth and will not produce any geomagnetic consequences.

 Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat’s Paw Nebula visible in Scorpius. At 5,500 light years distant, Cat’s Paw is an emission nebula with a red color that originates from an abundance of ionized hydrogen atoms. Alternatively known as the Bear Claw Nebula or NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. Pictured above is a deep field image of the Cat’s Paw nebula.

 About 7,500 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop.
NGC 6992 is  east part of  the Veil Nebula,  it lies about 1,400 light-years distant.
