On 28 May 2016 the star pointed to by the arrow appeared in our sky for the first time. It is supernova 2016coj, which exploded inside the elliptical galaxy NGC 4125 that surrounds it in this image. At the time of this photograph on 28 May 2016 the supernova shone at about magnitude 14.5, but by mid-June 2016 it was up to magnitude 13, making it one of the brightest supernovae of the last several years. Note the much smaller but bright galaxy below NGC 4125; this is NGC 4121. The dim galaxy at top center is UGC 7110, while the tiny edge-on galaxy at the bottom right is PGC 38406.
