  Rod Stubbings comments:

V342 Cen:
The position agrees more with the ROSAT  ID. (11h07 15.4  -55 57' 40") It's
interesting to see that no star is shown on the DSS images but present on
the USNO-A2.0 data.

  This may suggest a large-amplitude dwarf nova (amplitude exceeding 6 mag?)
or other kind of CV with large light variation.

  Follow-up observations, esp. time-series photometry, are strongly
encouraged.  Accurate astrometry is also very welcomed to securely identify
the quiescent counterpart.

  ROSAT ID information: [vsnet-chat 3231]

  Object information:

[vsnet 1307]

  In ASP Conf. Ser. 1, 67, Steiner et al. listed southern CV candidates
selected from irregular variable stars in GCVS.  All of them have quite
blue colors; some were confirmed by spectroscopy.
