COMET LOVAS (1980s)
     The following approximate positions have been reported:

     1980 UT          R. A. (1950) Decl.     m1     Observer
     Dec.  9.00623    9 12.8     +33 39      17     Lovas
          14.46111    9 12.7     +33 41      17     Kowal

M. Lovas (Konkoly Observatory).  Object diffuse with condensation,
   nothing reported about a tail.  Communicated by B. Szeidl.
C. Kowal (Palomar Mountain Observatory).  1.2-m Schmidt telescope.
   Accidental independent discovery.  Object fairly well condensed,
   no tail.  Daily motion ~ 2' due west.


1980 RG1
     This object (cf. IAUC 3522) was recovered by C. Kowal with the
l.2-m Palomar Schmidt at the following dark run, as follows:

     1980 UT             R. A. (1950) Decl.        Mag.
     Oct. 14.24167     0 13 01.78   +11 20 17.8    17
          14.26250     0 13 02.14   +11 20 08.9

     Computations by the undersigned lead to a = 2.64 AU, e = 0.47
(q = 1.41 AU), Incl. = 4o.4.  Further details will be given on the 1981
Jan. 1 batch of MPCs.


HONDA'S VARIABLE IN CYGNUS (NOVA CYGNI 1980)
     J. Mattei, American Association of Variable Star Observers,
reports that E. Waagen has found this object to be bright on three of
24 randomly selected Harvard photographic plates, namely, on 1945
Nov. 6, 1946 Aug. 6 and 1950 Nov. 6.  Between 1938 and 1951 the
object varied in brightness from mag > 14 to mag ~ 10.  A check of
the Palomar Sky Survey prints showed a bright red image at the
position.

     E. Ney, O'Brien Observatory, University of Minnesota, reports
that f_nu ~ 9 Jy beteen 1 and 10 um.  Magnitudes on Dec. 13.94 UT
were: R = 7.8; I = 6.9; 1.2 um, 5.8; 1.6 um, 5.0; 2.2 um, 4.6; 3.5
um, 3.95; 4.8 um, 3.2; 8.5 um, 2.2; 10.6 um, 1.4.
