Circular No. 4278 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 617-495-7244/7440/7444 (1179) MALLY L. D. Schmadel, Astronomisches Rechen-Institut; and R. M. West, European Southern Observatory, report the recovery of this faint, long-lost minor planet. Following West's remeasurement of the 1931 Heidelberg plates and Schmadel's recomputation of the orbit, a plate pair was exposed by H.-E. Schuster with the 1.0-m ESO Schmidt at the expected favorable opposition in 1986 Mar. A candidate found on the line of variation was only 111' from the prediction. Identity with (1179) was confirmed by the discovery of additional images on a U.K. Schmidt plate in 1983 July, ESO Schmidt plates on three nights in 1979 Dec. and on the 1952 Jan. Palomar Sky Survey exposures. West's measurements at the five oppositions and Schmadel's orbit linking them will be published on the Dec. 16 MPCs. There are no additional identifications of the object among previously reported observations of minor planets. NOVA CENTAURI 1986 Photoelectric observations by P. Birch and R.
