C/1996 Q1 (Tabur) is a non-periodic comets that was expected to appear in the naked eye in but faded rapidly before doing so in 1996. It is the first of three comets discovered by Australian astronomer, Vello Tabur.
Discovery and observations
The comet was first spotted by Vello Tabur from his 0.2 m (7.9 in) reflector as a 10th-magnitude object within the constellation Eridanus on the evening of 19 August 1996. At the time, astronomers had difficulty confirming the new comet's existence until Herman Mikuž and Alan Hale independently spotted it on 21 August.
The comet steadily brightened as it approached the Earth throughout the entire month of September, with some astronomers hoping it would reach naked eye visibility by the end of the month. However, it only reached a peak magnitude of 4.8 on 7 October 1996 before it faded rapidly in the course of three weeks. It was theorized that the comet's sudden decline in brightness were likely caused by the depletion of volatiles within its nucleus.
The comet was last seen as a 9th-magnitude object on 23 November 1996.
Orbit
Shortly after discovery, Brian G. Marsden computed the first parabolic orbit of the comet on 23 August 1996, which was roughly 73 degrees inclined to the ecliptic and an orbital period of approximately 18,500 years. A revised orbit was published about a week later, and Jost Jahn noted it has a strong resemblance to the orbit of C/1988 A1 (Liller), suggesting it might have fragmented from each other in a previous perihelion, despite the latter's shorter orbital period of 2,900 years. In the following years, more fragments of the same comet family were found. These were C/2015 F3 (SWAN), C/2019 Y4 (ATLAS) and C/2023 V5 (Leonard).
