Members of the LAS independently discovered a supernova type 1a-p in NGC6146 on the 29/05/09.
The supernova occurred sometime between 24/05/09 and the 29/05/09; we know this as we imaged the galaxy on the 24th and no sign of a supernova. The host galaxy is NGC6146 (mag. 14) which lies in the constellation of Hercules some 390 million light years away and is an elliptical galaxy. The supernova is a type1a-p (mag. 19.5 +or- 0.5) which suggests it was one of a binary system.
