Great Comet of 1901

The Great Comet of 1901, sometimes known as Comet Viscara, formally designated C/1901 G1 (and in the older nomenclature as 1901 I and 1901a), was a comet which became bright in the spring of 1901. Visible exclusively (or almost exclusively) from the southern hemisphere, it was discovered on the morning of April 12, 1901 as a naked-eye object of second magnitude with a short tail. On the day of perihelion passage, the comet's head was reported as deep yellowish in color, trailing a 10-degree tail. It was last seen by the naked eye on May 23.
