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. Marsden
