COMET C/2018 C2 (Lemmon)
The prefix for this object is being changed from A/ to C/, following the
receipt of the following message from M. Micheli: "We obtained two 60-second
r-filtered exposures of A/2018 C2 using the Canada-France-Hawaii Telescope on
2018 March 22.6 UT. The queue observer was David Woodworth. The object is
cometary, displaying a broad faint tail of about 10" toward the West. The coma
is only marginally extended, with a FWHM of 0.9" compared to 0.8" of nearby
stars."
