COMET LOVAS (1977c)
     The following positions have been reported:

     1977 UT             R. A. (1950) Decl.        m1  m2   Observer
     Feb. 17.94010    10 36 29.70   +35 13 54.2   15        Lovas
          23.91093    10 31 11.13   +34 58 40.9   15          "
     Mar. 16.92569    10 13.7       +33 15        15          "
          20.10223    10 11.3       +33 16            17-18 McCrosky

M. Lovas (Konkoly Observatory).  Comet diffuse with condensation,
   tail < 1o.
R. E. McCrosky (Harvard Observatory).  Diffuse, possible tail.

     Computations by the undersigned suggest that Decl. on Mar. 16
requires correction by -20' and that the comet has a large perihelion
distance.  The following ephemeris is supplied:

     1977 ET     R. A. (1950) Decl.     Delta     r      m2
