30100 Christophergo           Discovered 2000 Mar. 11 by the Catalina Sky Survey.
Christopher Go (b. 1970) is a Philippine astrophotographer who has taken superb images of the moon and planets since 1990. His detailed images of eclipses of the Galilean moons of Jupiter attest to the excellent quality of his work with a 0.28-m telescope. In 2006 he discovered the Red Spot Jr. on Jupiter.
