Circular No. 3260 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Postal Address: Central Bureau for Astronomical Telegrams Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. TWX 710-320-6842 ASTROGRAM CAM Telephone 617-864-5758 COMET HANEDA-CAMPOS (1978j) On IAUC 3259 we neglected to remark that observers Haneda, Campos, McCrosky and also Bennett (who confirmed the discovery) all described the comet as diffuse, with condensation, without tail. Further precise positions have been reported as follows: 1978 UT R. A. (1950) Decl. m1 Observer Sept. 2.16782 20 51 53.58 -29 46 49.8 Schwartz 2.57153 20 52 28.21 -29 59 32.7 10 Candy 2.58472 20 52 29.11 -29 59 59.4 " 4.52396 20 55 29.20 -31 05 10.7 10 Johnson 4.59618 20 55 35.29 -31 01 39.0 " 5.15968 20 56 33.15 -31 27 23.8 Schwartz G. Schwartz (Harvard College Observatory, Agassiz Station). 155-cm reflector and 41-cm astrograph. Measurers: R. E. McCrosky and C.-Y. Shao. The positions given on IAUC 3259 have been slightly revised. M. P. Candy and J. Johnson (Perth Observatory, Bickley). Object diffuse with condensation, tail < 1o. 33-cm astrograph. J. Bortle, Brooks Observatory, provides the following total visual magnitude estimate (32-cm reflector): Sept. 5.10 UT, 11.2. The following elliptical elements have been calculated. The ephemeris is from the second set, which suggest that the comet made a close approach to Jupiter in 1969. M. P. Candy B. G. Marsden (6 obs. Sept. 2-4) (9 obs.
