Comet C/1996 B2 Hyakutake
On January 31, 1996, IAU circular 6299 reported the visual discovery
of a comet by Yuji Hyakutake of Japan.
Comet Hyakutake, also designated Comet C/1996 B2,
approached within 0.1 AU of the Earth
(about 15 million km) on March 25. Perihelion on May 1
saw the comet at a distance of 0.23 AU from the Sun.
After perihelion, the comet should be visible in the southern hemisphere
from the middle of May to early June.
