C/1862 N1 (Schmidt), sometimes referred to as C/1862 N1 (Schmidt–Temple), is a non-periodic comet discovered by Johann Friedrich Julius Schmidt on 2 July 1862.

Observational history

[edit]

The comet was discovered on 2 July 1862 Johann Friedrich Julius Schmidt, then director of the National Observatory of Athens, and a few hours later was discovered by Wilhelm Tempel, at Marseille Observatory. The comet upon discovery was located in the constellation Cassiopeia and Schmidt described the comet as being tailless, with a coma 22 arcminutes across, and visible with the naked eye. Temple estimated its magnitude to be 4–5. Schmidt observed the comet again on July 4 and noted a tail half a degree long.[2]

The comet passed at a distance of 0.0982 astronomical units (14,690,000 km; 9,130,000 mi) from Earth on 4 July, making it the fourth closest known approach of a comet to Earth in the 19th century.[3] Consequently the comet moved away from both the Earth and the Sun, while brightening moonlight hampered observations. The comet was last observed with the naked eye on 7 July. The comet faded rapidly throughout the month and it was last observed on 31 July.[2]

Meteors

[edit]

The comet has been tentatively associated with the weak meteor shower ζ Arietids, observed between 13 and 25 August. The minimum orbital intersection distance between the comet and Earth is 0.028 AU.[4][5]
