CPD -48 1577
     R. F. Garrison, David Dunlap Observatory: W. A. Hiltner,
University of Michigan: and R. E. Schild, Center for Astrophysics,
write: "The star CPD -48 1577 has been found to have a spectrum
characteristic of the cataclysmic variables, and at V = 9.8 it
would be the brightest known such object.  It has colors similar
to those of UX UMa and flickering brightness fluctuations of order
0.1 mag on a timescale of minutes.  Larger variations were found
on a timescale of years.  The extremely broad, shallow H absorption
lines have emission cores with a very slow Balmer decrement.
Extremely weak, broad absorption lines of He I and He II are probably
present."


1982 October 8                 (3730)              Brian G. Marsden
