Comet Hale-Bopp was one of the intrinsically brightest of comets in recorded
Unfortunately it never ventured close to the Earth, but still managed to achieve "great comet" status.
It was predominantly observable from the Northern hemisphere at its best during April 1997.
By May 1997, Southern hemisphere observers were able to pick it up, low in the north west after sunset.

The Earth was crossing the comets orbital plane at the time, enabling enhanced visibility of the dust tail.
It can be traced over 8 degrees towards Canopus.
