PROBABLE NOVA IN SCORPIUS
     P. M. Kilmartin communicates the following position from an
exposure by A. C. Gilmore at Mount John Observatory with the 0.15-m
astrograph on May 26.4 UT:  R.A. = 17h03m42s.69, Decl. =
-43 11'26".5 (equinox 1950.0; mean residuals 0".25 in R.A., 0".47
in Decl.).


NO SUPERNOVAE 1992W, 1992X
     J. Mueller, Palomar Observatory, reports that a complete
reduction by W. Sargent of the spectra mentioned on IAUC 5517
indicates that a preliminary misinterpretation occurred and that the
objects called SN 1992W in MCG +08-23-096 and SN 1992X in MCG
+06-32-024 are both actually foreground M-dwarf stars.
