Comet Lemmon Fly Through (May 3, 2013)

Comet C/2012 F6 (Lemmon), which was discovered in March of 2012 by a survey at the Mt. Lemmon Observatory in Arizona, glided through the widest-angle imager of the STEREO (Ahead) spacecraft during a two-week period (April 17-30, 2013). With the Sun to the right and the Earth to the left, we could watch as its ion tail was always being pushed away from the Sun by the solar wind; a dust tail is also visible. A few coronal mass ejections can be seen as well blasting towards the general direction of Earth during this period, as well as a series of puffs of solar wind. http://sohowww.nascom.nasa.gov/pickoftheweek/
