POSSIBLE NOVA
     W. Liller, Vina del Mar, Chile, reports his discovery of an
apparent nova (mag 8.5) on a Technical Pan photographs taken with
Problicom on June 5.085 and 5.087 UT with an 85-mm camera lens (+
orange filter), located at R.A. = 17h54m.2, Decl. = -30o02'
(equinox 2000.0).  Nothing brighter than mag 11.5 appears at this
location on a photograph taken on June 2.09.  CCD magnitude on June
6.120:  V = 9.0 (GSC comparison stars).


SUPERNOVA 1997cq IN ANONYMOUS GALAXY
     S. Jha, P. Garnavich, P. Challis, and R. Kirshner, Harvard-
Smithsonian Center for Astrophysics, report that a spectrogram of
SN 1997cq (cf. IAUC 6674), taken by P. Berlind on June 5.34 UT at
the Whipple Observatory 1.5-m telescope, shows it to be a type-IIn
supernova at a redshift of z = 0.032.  The spectrum shows narrow
H-alpha emission, characteristic of type IIn, with a broader
underlying component of width 2800 km/s FWHM.  Images taken
concurrently with the 1.2-m telescope by L. Macri and D. Koranyi
yield magnitudes V = 19.0 and R = 18.9.
     A. V. Filippenko and D. C. Leonard, University of California
at Berkeley, report that CCD spectra (range 320-1000 nm) obtained
with the Lick 3-m Shane reflector on June 6 show that SN 1997cq is
a peculiar type-II supernova (formally known as type IIn),
dominated by relatively narrow (FWHM < 1000 km/s) Balmer emission
lines on a featureless continuum.
