SuperNova2012aw

　＊　しし座超新星2012aw　＊

On 25.5 July 2013 the Lick Observatory Supernova Search reported a possible supernova in Messier 74. On 28.02 July, the Celestron c14 robotic unit was slewed to that transient, confirming it, despite the very strong interference of a waning Moon within 20 deg from M74. A report was sent to the central Bureau for Astronomical Telegrams (CBAT), which issued the CBET 3606 circular, announcing the discovery, including the contribution from the Virtual Telescope. The supernova was quite bright (mag. 12.8 R unfiltered), at this time being the brightest supernova in the sky in apparent magnitude. Spectroscopy showed this was a type II supernova. It is now called SN 2013ej.
