arXiv:1504.01864
Abstract
We present CCD BVRI photometry for PSN J07285387+3349106 in NGC 2388 collected from 2015 February 17 until March 17. Decaying by 3.6 mag in the R band in the first 20 days post-maximum, this object is among the fastest supernovae observed to date. The peak absolute R magnitude exceeds -18.7 and may be as high as -20.1.
