COMET LOVAS (1976k)
     T. Seki, Geisei, provides the following precise positions,
those on Nov. 23 and 26 being preferable to those reported earlier:

     1976 UT             R. A. (1950) Decl.
     Nov. 23.73993     9 20 20.13   +72 12 45.1
          26.84722     9 15 58.82   +72 25 23.5
     Dec.  3.83889     9 04 15.77   +72 51 41.0

     The following elements, by B. G. Marsden, are still uncertain
but probably preferable to those on IAUC 3016.  Changes to the ephemeris
are: Jan. 7, dR.A. = -0m.9, dDecl. = -0'.4; Feb. 6, -2m.05, -6'.4.

       T = 1976 Oct. 2.232 ET    Peri. = 127.421
                                 Node  = 285.140   1950.0
       q = 5.91294 AU            Incl. =  86.784


COMET LOVAS (1974c)
     A. C. Gilmore, Wellington, provides the following precise
positions, those on July 26 obtained with the 61-cm reflector at Mount
John University Observatory, the others with the 41-cm reflector at
the Carter Observatory.  Measurer: P. M. Kilmartin.

     1976 UT             R. A. (1950) Decl.         m2
     July 26.66312     0 58 46.63   -22 09 17.7    16.5
          26.71613     0 58 45.73   -22 09 18.0

EMISSION VARIABLE IN SAGITTA
     G. M. Hurst, Northampton, England, reports that his reductions
from Tri-X exposures by Baguley, Manning and Pennell show this star
(cf. IAUC 2995, 3005) at photovisual magnitude 11.0-11.3 on Aug. 6
and 19 (pre-announcement) and Nov. 3 and 13.  Red survey (GAF 200
film) photographs by P. Birtwhistle show the star to be extremely
red, the following magnitudes being from comparison with image sizes
of six BD stars: May 20, 9.3; June 6, 9.3; July 21, 9.5; Nov. 2, 9.5.


1976 December 17               (3018)              Brian G. Marsden
