POSSIBLE NOVA IN SAGITTARIUS
     On Nov. 6 W. Liller, Vina del Mar, Chile, reported his discovery
of a possible nova at R.A. = 18h05m44s6, Decl. = -26deg16'44" (equinox
1950.0, uncertainty 10").  Orange-filter magnitudes were: Nov. 2.02
UT, 10.7; 5.04, 10.6.  An objective-prism red photograph showed
continuum and possible weak emission at H-alpha.  Confirmation from
other observatories is not yet available.
