Comet Coddington–Pauly, formally designated as C/1898 L1, is a hyperbolic comet that was visible through telescopes between 1898 and 1899. It is the second comet ever discovered through photography (after 206P/Barnard–Boattini), and the only comet discovered by astronomers Edwin Foster Coddington and Wolfgang Pauly, respectively.

Discovery and observations

Edwin Foster Coddington made a 2-hour exposure of the Rho Ophiuchi cloud complex on the night of 10 June 1898, however the plates weren't developed until two days later. There he found a "strong nebulous trail" only about 2–3 degrees north of the star, Antares, where his colleague, William J. Hussey, confirmed it was a comet. It was later discovered independently by Romanian astronomer, Wolfgang Pauly, while observing the Messier 4 globular cluster on 14 June 1898.

Notes

  1. Contemporary sources note C/1898 L1 as the third comet discovered photographically after a supposed "comet-like" object spotted by J. Martin Schaeberle during the solar eclipse of April 16, 1893. However, it turned out to be a disconnected coronal mass ejection rather than being an actual comet itself.
  2. On the night of 12 June 1898, W. J. Hussey reported the comet's position on the following coordinates: α = 16 24.9 , δ = –25° 14′
