COMET GEORGE (1989e1)
     Douglas B. George, Kanata, near Ottawa, reports his visual
discovery of a comet.  The following observations are available:

     1989 UT           R.A. (1950) Decl.        m1       Observer
     Dec. 18.031      19 52.3      +25 30      13        George
          19.073      19 54.2      +25 35      10.5      Hale
          19.115      19 54.4      +25 32      10.4      Levy

D. B. George (Kanata, ON).  0.40-m reflector.
A. Hale (Las Cruces, NM).  0.41-m reflector.  Object diffuse with
  central brightening.
D. Levy (Tucson, AZ).  0.41-m reflector.  Comet diffuse with slight
  condensation and 2' coma; faint sunward fan at p.a. 240 deg.


NGC 7078
     H. Lehto, G. Machin, I. McHardy, and P. Callanan, Department
of Astrophysics, University of Oxford; and P. Charles, Royal
Greenwich Observatory, report:  "We have made Very Large Array
observations at 6 cm in 1989 Feb. of the globular cluster NGC 7078
(M15).  A deep map (rms 28 mJy) revealed the presence of a 185-mJy
source in the core of the cluster at a position of R.A.
= 21h27m33s.28, Decl. = +11 56'50".9 (equinox 1950.0) with an
uncertainty of +/- 0".4.  The coincidence of this position with AC
211, the optical counterpart of the x-ray source (Geffert et al.
1989, A.Ap. 209, 423), implies that the x-ray system is the source
of the emission.  There is evidence that the emission region is
extended."
