Comet Skorichenko–George (sometimes spelled Scorichenko–George) is also designated C/1989 Y1, 1990 VI, and 1989e1. It was discovered on December 17, 1989 by Doug George of Kanata (near Ottawa), Ontario, Canada , and Soviet astronomer Boris Skoritchenko (Mezmay, Krasnodar Krai). Skoritchenko was using 8×20 binoculars,[2] whilst George was using a 16" reflector and had searched for 65 hours. The comet was magnitude 10.5 in the northern evening sky. It passed its perihelion on April 11, 1990 at a distant 1.57 AU,[3] and remained in the Earth's evening sky through April 1990, at magnitude 9–10.
C2 emission bands were observed in the comet Skorichenko-George.
