Circular No. 3678 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 1982 EA J. Gibson, Jet Propulsion Laboratory, reports the following observations of another fast-moving asteroidal object, recorded on exposures taken for 1982 DB with the 1.2-m Palomar Schmidt: 1982 UT R. A. (1950) Decl. Mag. Mar. 3.50489 13 38 21.50 -18 27 14.7 17 4.37711 13 35 58.84 -18 29 54.6 The following serniaccurate positions have been obtained at the European Southern Observatory by H.-E. Schuster and H. Mauder: 1982 UT R. A. (1950) Decl. Observer Mar. 5.20069 12 22 19.9 -27 43 51 Schuster 6.19722 12 25 49.8 -28 09 52 " 7.17917 12 29 28.5 -28 36 43 " 7.290 12 29 52 -28 40.3 Mauder 9.17083 12 37 08.6 -29 30 12 Schuster Mauder telexes the following photometric data, obtained on Mar. 7.290: V = 14.1, B-V = +0.9, U-B = +0.7. Preliminary computations by the undersigned suggest that this is an Amor-type object (q = 1.09 AU, e = 0.39, Incl. = 5o, minimum Delta 0.12 AU in early April). PERIODIC COMET DU TOIT-HARTLEY (1982b, 1982c) Further observations show that comet 1982b continues to become fainter and more diffuse, while comet 1982c brightens. Nevertheless, comet 1982b (and apparently not 1982c) was observed spectroscopically by H. Spinrad with the 3-m reflector at the Lick Observatory on Feb. 25.4 UT. Moderate CN emission was detected, but there was no C2. The continuum was quite pronounced. SUPERNOVA IN NGC 2268 R. Wood, Royal Greenwich Observatory, provides the following precise position, derived from a single plate taken on Feb. 21 at mpg = 14: R.A. = 7h01m05s.12, Decl. = +84o28'04".2 (+/- 0".3; equinox 1950.0). 1982 March 10 (3678) Brian G.
