C/2015 V2 (Johnson) was discovered on 3 November 2015 by Jess Johnson (Catalina Sky Survey), using a 0.68-meter Schmidt–Cassegrain telescope. At the time of discovery the comet had an apparent magnitude of 17.1. Its incoming orbit had a Semimajor Axis of 59,200 AU, but after crossing its perihelion the orbit will become hyperbolic with an eccentricity of 1.0009, thus C/2015 V2 will leave the Solar System. This image shows the comet on the night of April 26th 2017 at 0:20 a.m. UT.
