The perihel passage was on February 24th 1996 just outside earth orbit at a distance of 190 millions km.
At perigeum I saw a tail at least 15 degrees long.
This comet was discovered by the amateur comet hunter Yuji Hyakutake who lives in
Kagoshima in the souther Japan. On the morning of December 26th 1995 he found the
faint glow in the intersection of Virgo, Libra and Hydra with his impressive 25X150
binoculars. The magnitude was 10.5 with a diameter of 3.5'.
