MT Pup: long-term monitoring program

   During the course of ROSAT source identification, I have noticed the
following neglected CV (MT Pup) with a large amplitude.  Please put this
on long-term monitoring program to clarify the nature of variability.

   Registered as a large-amplitude eclipsing binary in GCVS, but the X-ray
is exceptionally strong.  Please note MT Pup was once suspected to be an
R CrB star.  Kilkenny (1989) in Observatory 109, 229 classified this star
as a CV, which is consistent with the X-ray characterstic.  More observations
are undoubtedly needed!

   MT Pup:

075411.9 -143916 (2000.0) PUPMT * E: 15 19 P 31090.47 - - R0/AN290U

   ROSAT:

075412.1 -143904 (2000.0) 1RXS-F_J075412.2-143905 0.060 1.00 0.30
