Discovery and observations

On the morning of 13 November 1974, John Caister Bennett discovered his second comet as a diffuse 9th-magnitude object in the constellation Hydra using a 125 mm (4.9 in) refractor from Pretoria, South Africa.^[b] He had spent a total of 482 hours searching for a new comet since his first discovery in 1969. At the time, the comet had no discernible coma nor tail, however Bennett was of the opinion it experienced an outburst lasting about five days just before discovery^[7]
