COMET LOVAS (1977c)
     B. Szeidl, Konkoly Observatory, cables that M. Lovas has
confirmed his discovery of the possible comet reported on IAUC 3041:

     1977 UT          R. A. (1950) Decl.      m1
     Feb. 23.836     10 31.2     +34 59       15

The daily motion specified, dR.A. = -0m.90, dDecl. = -3', suggests that
the time of the first observation was about Feb. 17.95 UT.  The object
is diffuse with condensation and a tail < 1o long.


1936 CA (ADONIS)
     H.-E. Schuster, European Southern Observatory, telexes the
following confirmatory observations of Kowal's recovery of this object:

     1977 UT          R. A. (1950) Decl.      mpg
     Feb. 24.21597   10 25.5     +11 32       18.5
          25.19861   10 21.7     +11 47       18.5

     An improved fit to the 1936 and 1977 observations, by B. G.
Marsden, yields the elements given below.  The minimum distances
from Venus in 1964 and the earth in 1943 are now found to be 0.04
and 0.08 AU, respectively (cf. IAUC 3041).

       T = 1976 Dec. 16.0812 ET   Epoch = 1977 Feb. 26.0 ET
   Peri. =  41.0062                   e =   0.764224
   Node  = 351.2499   1950.0          a =   1.872546 AU
   Incl. =   1.3688                   n =   0.3846407
       q =   0.441501 AU              P =   2.562 years


PERIODIC COMET GEHRELS 3 (1975o)
     The following precise positions were obtained by G. Schwartz
and C. Y. Shao with the 155-cm reflector at Harvard College
Observatory's Agassiz Station.  Measurers: Shao and J. H. Bulger.

     1976 UT             R. A. (1950) Decl.
     Oct. 23.38262     6 41 29.43   +22 38 09.1
     Nov. 20.36187     6 41 03.52   +22 28 53.7
     Dec. 16.30740     6 26 58.37   +22 31 49.0


1977 February 25               (3042)              Brian G. Marsden
