COMET BENNETT (1974h)
Mr. A. C. Gilmore, Carter Observatory, provides the following
precise positions, obtained with the 10-cm f/10 astrograph. There
is no obvious change in total brightness (cf. the observations by
T. Seki on IAUC 2724), but the comet is large and diffuse, and the
condensation has become weaker. Measurer: Pamela M. Kilmartin.
