Just wandering whether there is a supernova in the galaxy NGC 4156? Looking other peoples images, it seems to me that at some point this year a very bright spot has appeared to the galaxy.

The attached image is an unprocessed stack of luminance frames acquired at April 01-02 and 15-16. What do you think?
