One of the cool things about observing comets and asteroids is one gets see how a comet's coma and  tail develops as they approach perihelion. when Comet C/2015 V2 (JOHNSON)  was on The Possible Comet Confirmation Page(PCCP) it was just small faint spot on CCD image now it is around magnitude 8 in range of a backyard telescope or nice set of binoculars.
