     Y. Kozai, Tokyo Astronomical Observatory, cables that Y.
Kuwano, Hita, Oita, has discovered a novalike object as follows:

     1977 UT          R. A. (1950) Decl.      mpv
     Mar. 27.80556   18 35.2     -23 23       9.3

     This comet has been recovered by C. Y. Shao and G. Schwartz on
exposures obtained with the 155-cm reflector at the Agassiz Station
of the Harvard College Observatory, as shown below.  The comet is
almost stellar in appearance and very close to the position predicted
on IAUC 3007.  Measurer: Shao.

     1977 UT             R. A. (1950) Decl.         m2
     Mar. 27.22560    12 36 53.01   +14 00 51.9   ~19.5
          27.35161    12 36 46.14   +14 01 49.3

     The following precise position was obtained by H. Kosai with
the 105-cm Schmidt telescope at Tokyo Observatory's Kiso Station:

     1977 UT             R. A. (1950) Decl.         m1
     Mar. 12.56196    10 16 55.19   +33 54 43.2    16

     D. Seargent, The Entrance, New South Wales, provides the
following total visual magnitude estimates (20 x 65 binoculars): Mar.
17.50 UT, 10.5-11.0; 18.50, 10.5-11.0; 24.58, 10.

     G. Sitarski (1964, Acta Astron. 14, 25) has drawn attention to
the possibility of observing meteors from P/Grigg-Skjellerup this
year.  The earth will reach the ascending node of the comet's orbit
on Apr. 23.3 UT, only 12 days after the comet.  The theoretical
radiant is R.A. = 109o.6 = 7h18m, Decl. = -44o.3 (equinox 1950.0).
According to Baggaley (1973, Observatory 93, 23), some radio meteors
associated with the comet were observed in 1972.  See also IAUC 2371.

1977 March 30                  (3055)              Brian G. Marsden
