[vsnet-campaign-dn 5479] DM CMa: possible ROSAT ID, CV?

[Taichi Kato]

   I noticed that DM CMa (GCVS type M) may be identified with
a ROSAT source.

065245.6 -142145 (2000.0) 1RXS-F_J065245.6-142145 0.029 0.33 0.40

   There is no prominent red star as suggested from the literature
spectral type of M0:.  The more likely interpretation would be
a cataclysmic (or related) object at the position of Kinnunen & Skiff
(2000).  ASAS data are a little too noisy to draw a definite conclusion.
Probably an object worth watching.
