(vsnet 503, 1996 Jan. 24)
Dear CV fans,
In a preprint just arrived from STScI, R. A. Downes & D. Wallace present new spectroscopy of several suspected variable stars, and Is-type (rapidly, irregularly variable) stars in GCVS. This paper will appear in the Feb. issue of PASP.
Among the observed objects, they describe BE CVn as a possible dwarf nova, which showed weak, broad H-beta absorption and very weak H-alpha absorption on a blue continuum.
BE CVn is included in GCVS 4 with the following information:
12h 15m 30s +40o 49'.7 (1950) type: Is: mag: 16.0-18.1p
Observations (especially CCD) are encouraged.
Regards,
Taichi Kato
