A very unique CBET 3607 has just been released by the IAU announcing both last years supernova as SN2012im (until now it did not have a cbet or IAU designation) and this current discovery as SN2013ek. It ties them both together and encourages follow up to find out just what has actually happened.
The CBET notes two possible interpretations - two nearby explosions or a non terminal explosion of the same object. To my knowledge there had never been two supernova occur this close and within 1 year almost to the day of each other. Colin Drescher BOSS team member put forward an interesting idea - could the one supernova trigger a chain reaction SN in a nearby star?
