CE-315

   According to astro-ph/0103355, M. T. Ruiz et al. discovered a ultra-short
period CV (helium CV like GP Com) in their proper motion survey program.
The object shows strong emission lines of He I and He II.  The binary
period is 65.1+/-0.7 min, which seems to make the system something
intermediate between helium CVs and V485 Cen-like system.
Since the object is expected to show outbursts as in other similar systems,
we encourge observers to monitor this object closely, and report if
any brightening is caught.  If the object erupts, we are willing to make
an extensive VSNET campaign!  The object is normally at mag 17-18.

   CE-315  13h12m46s.5 -23o21'31" (J2000.0)

   Other identifications include Luyten's high proper motion star, and
ROSAT detection.
