(2060) CHIRON
K.J.Meech, University of Hawaii and M.J.S.Belton, Kitt Peak
National Observatory, report that (2060) Chiron has a COMA.
Observations made using a CCD at the prime focus of the KPNO 4-m
telescope on Apr.10UT in nearly photometric conditions showed the
feature, which was of very low surface brightness, extending
mostly to the southeast for about 5". The seeing was such that
the FWHM image of Chiron had a diameter of 0.9" and the very
approximate Mould r mag was 16.4. The coma had the same general
appearance on Apr.11 in slightly poorer seeing.   IAUC 4770
