Bright variable star in Cassiopeia.

TUCKER R.

Abstract (from CDS):

R. Tucker, Tucson, AZ, reports the following astrometry of this variable star from several CCD images: R.A. = 0h09m21s.98 ± 0s.02, Decl. = +54d39'45".6 ± 1".6 (equinox 2000.0). Tucker provides the following V magnitudes for the variable: Nov. 1.148 UT, 9.2; 1.188, 9.3; 2.089, 9.3. A star of red mag 12.0 is visible on a Digitized Sky Survey U.K. Schmidt plate from Sept. 19.319, and he measures position end figures for that star: 21s.97, 44".0. (There is also a nearby star of red mag 11.9-12.0 located at position end figures 24s.66 ± 0s.02, 40'08".4.) Tucker adds that his spectra taken with a 0.36-m Schmidt-Cassegrain telescope (+ SBIG SGS spectrograph; range 421.9-750.4 nm; disperson 0.43 nm/pixel) shows hydrogen absorption lines fading in intensity between Nov. 1.17 and 2.12; the spectrum appears very similar to that of a star of spectral class A7 except for a weak emission feature at 466.7 nm.
