SUPERNOVA 1991L IN MCG +07-34-134
     C. Pollas, Observatoire de la Cote d'Azur, reports his discovery
of an apparent supernova in MCG +07-34-134 = IRAS 16395+3923,
found on plates obtained Feb. 24.17, 25.17, and 26.17 UT with the
OCA Schmidt telescope by A. Maury and himself.  SN 1991L, of magnitude
R = 18, is located at R.A. = 16h39m32s.73, Decl. = +39 23'13".6
(equinox 1950.0), or 2".5 west and 8".2 north of the center of the
western part of this unusual galaxy system that is described as a
pair.  A nearby star (R = 14.5) is located at R.A. = 16h39m37s.59,
Decl. = +39 23'23".7.


SUPERNOVAE 1991D AND 1991H
     A. V. Filippenko and J. C. Shields, University of California at
Berkeley, report that CCD spectra (range 390-700 nm, resolution 1-2
nm), obtained on Feb. 23 UT with the Shane 3-m reflector at Lick
Observatory, confirm that SN 1991D (cf. IAUC 5185) and SN 1991H (cf. IAUC
5188) are of types Ib and II, respectively.
