Comet C/1996 B2 (Hyakutake)

Our story moves to Japan and an amateur astronomer named Yuji Hyakutake. Yuji, who's surname means, a hundred Samurai, became interested in astronomy when,as a 15 year old boy, he witnessed the great comet C/1965 S1 (IkeyaSeki), this great sungrazer made him want to discover his own comet of equal greatness and the fact that this one was discovered by two Japanese observers only fuelled his enthusiasm.
