SUPERNOVAE 1988Z, 1989O, 1989Q, 1989R, 1989S
     R. Kirshner, B. Leibundgut, and C. Smith, Center for
Astrophysics, report observations of supernovae obtained at the
Multiple Mirror Telescope on Nov. 5 and 6:  "A spectrum of SN
1989S in IC 226 confirms the identification as a type-Ia supernova
several weeks past maximum (IAUC 4888).  A position for the galaxy
is R.A. = 2h24m50s.9; Decl. = +27 59'09" (equinox 1950.0; accuracy
better than 2") and for the supernova is R.A. = 2h24m51s.7; Decl.
= +27 58'39".  A spectrum of SN 1989R in UGC 2912 shows that the
narrow H-alpha reported earlier (IAUC 4871, 4873) persists with
FWHM < 1800 km/s and no strong P-Cyg feature.  The galaxy position
is R.A. = 3h56m06s.8; Decl. = +42 28'31", while the SN is at
R.A. = 3h56m06s.0; Decl. = +42 28'40".  SN 1989Q in an anonymous
galaxy shows a type-Ia spectrum several months past maximum,
confirming the report on IAUC 4888.  The redshift of the galaxy
is z about 0.059.  The unusual supernova 1989O in MCG 6-1-26 has
faded very rapidly and is now fainter than mv = 21.  A spectrum
shows it is developing broad emission lines of uncertain
identification.  SN 1988Z in MCG +03-28-022 continues to show
very bright H-alpha, with FWHM about 2100 km/s.  The SN position is
R.A. = 10h49m10s.6; Decl. = +16 15'57", located 14".5 west and
30".9 north of a convenient star that is southeast of the galaxy.
The SN is roughly 4" south of an emission knot of comparable
brightness."


QY PERSEI
     L. Rosino, Asiago Astrophysical Observatory, reports that
the U-Gem variable QY Per, normally fainter than mag 20 (period
about 370 days) has been found at maximum, with mag about 14.9,
by G. Candeo on Schmidt plates taken Oct. 30 and 31 at Asiago.
Further observations are encouraged.
