LQ SAGITTARII
     P. Zhao and J. E. McClintock, Smithsonian Astrophysical
Observatory; and A. U. Landolt, Louisiana State University, write:
"LQ Sgr, a poorly known nova, is now in outburst; it is about 5 mag
brighter in B than it was during quiescence.  Its spectrum,
obtained at the Cerro Tololo Interamerican Observatory (CTIO) 4-m
telescope on July 2.3 UT, is that of an M giant.  LQ Sgr is probably
a symbiotic nova (i.e., RR-Tel class).  During its eruption in 1897,
it reached B = 13.  Observations with the CTIO 1-m and 0.91-m
telescopes give the following magnitudes and colors:  July 5.23, V
= 14.33, B-V = +1.57, U-B = +0.75; 6.24, V = 14.38, B-V = +1.55,
U-B = +0.85, V-R = +1.98, R-I = +2.69, V-I = +4.67; 8.20, V = 14.40,
B-V = +1.56, U-B = +0.87."


SUPERNOVA 1994U IN NGC 4948
     A. Boattini and M. Tombelli, Piazzano Observatory, Florence,
report the following precise position obtained on July 5.90 UT:
R.A. = 13h02m19s.85, Decl. = -7o40'47".8 (equinox 1950.0).
