NOVA IN M32
D. C. Leonard, P. M. Nied, M. R. Davis, and A. W. Shafter, San
Diego State University; T. R. Norris, California State University,
Chico; M. R. George, Harvard-Smithsonian Center for Astrophysics;
and A. Gal-Yam, California Institute of Technology, report on behalf
of the Caltech Core-Collapse Project (cf. IAUC 8405) that a CCD
spectrum (range 460-910 nm) of the apparent nova in M32 (cf. CBET 591),
obtained on Aug. 2 UT with the double spectrograph mounted on the
Palomar Observatory 5-m Hale telescope, confirms that it is indeed a
nova. Prominent H-alpha (FWHM = 1200 km/s) and H-beta, and weaker Fe
II, emission lines are visible in the spectrum. The peaks of the
slightly asymmetric Balmer lines indicate a velocity of recession of
about -180 km/s for the nova, strengthening the case for its
association with M32 (velocity of recession -200 km/s, from Huchra et
al. 1999, Ap.J. Suppl. 121, 287).
