NOVA IN THE LARGE MAGELLANIC CLOUD 1988 No. 2
     R. H. McNaught, Siding Spring Observatory, reports the discovery
by Gordon Garradd, Tamworth, N.S.W, of another nova in the LMC.
An exposure by McNaught on Oct. 13.5 UT with the Uppsala Southern
Schmidt telescope yields the following position:  R.A. = 5h08m14.02,
Decl. = -68 41'22.6 (equinox 1950.0; rms 0".2).  Magnitude estimates
by Garradd (300-mm telephoto lens + hypered 2415 film) and McNaught
(visual):  Oct. 7.49, [14.5 (Garradd); 12.48, 11.3 (Garradd); 12.49,
11.3 (Garradd); 13.40, 10.4 (McNaught).  Garradd notes that the nova
is very close to HV 5609, as plotted on the Hodge/Wright atlas.  A
photograph of the LMC taken 1988 Oct. 7.72 by M. Hartley with the
U.K. Schmidt Telescope shows no change to V magnitude 19 in the
general vicinity of the nova.


NOVA OPHIUCHI 1988
     D. K. Lynch, R. J. Rudy, and G. S. Rossano, Space Sciences
Laboratory, The Aerospace Corporation; and R. C. Puetter, University
of California at San Diego, report:  "We obtained near-infrared
observations of Nova Oph 1988 using a cooled Ge grating spectrometer with
a 7".5-diameter aperture on the Lick Observatory Shane 3-m telescope.
Moderate-resolution spectroscopy (lambda/Delta(lambda) = 400) on
Sept. 22.2 UT showed a weak continuum with moderate strength
Paschen emission lines beta(5-3) through eta(10-3) also present.
The strongest emission feature present was the He I 1083.0-nm
line which had a line-to-continuum ratio of over 100:1."

6.16, 10.6 (R. King, Duluth, MN); 7.82, 11.2 (A. Perez, Paris,
France); 9.86, 11.4 (S. Korth, Dusseldorf, W. Germany); 10.86,
11.7 (E. Schweitzer, Strasbourg, France); 11.50, 11.6 (A. Pearce,
Woodlands, W. Australia); 12.85, 11.6 (M. Verdenet, Bourbon-Lancy,
France); 13.89, 11.8 (P. Schmeer, Bischmisheim, W. Germany);
14.55, 12.0 (R. H. McNaught, Siding Spring Observatory);
15.86, 12.7 (Verdenet); 16.50, 13.6 (McNaught); 18.84, 14.5 (Verdenet);
28.44, [15.5 (McNaught); Oct. 2.38, 14.9 (A. Boattini, Piazzano, Italy).
