Comet C/2018 V1 (Machholz-Fujikawa-Iwamoto) is a parabolic-orbit comet discovered on 7 November 2018 by Donald Machholz, with perihelion on 3 December 2018. It is estimated to be between 8 and 10th magnitude from mid-November to mid-December 2018, visible in a small telescope. It was discovered by three amateur astronomers: by an observer in Colfax, California, USA and by two observers in Japan.[1][2] The observations by three astronomers result in the name for the comet, Machholz-Fujikawa-Iwamoto.[2][3]

The observer in the USA used an 18.5 inch reflecting telescope.[2]
