EG Cnc
------

    It seems to be this bright cataclysmic variable has been monitored only
by few observers.  Concerning recent report of possible positive detection
by T. Watanabe (vsnet-obs 1398 on Oct. 23; this observation has not been
confirmed), I would like to introduce this variable.

    EG Cnc was discovered by M. Huruhata as an eruptive variable (H11).
Only single outburst in 1977 has been recorded (IBVS No. 2401).  Although this
variable was initially designated as a nova-like object, R. McNaught
correctly identified the quiescence and suggested it to be more resemble
an infrequently outbursting dwarf nova like UZ Boo and WX Cet.

    Magnitude estimates reported in IBVS 2401 for the 1977 outburst:

         UT             mag
    1997 Nov.  9.8     [12.0
              12.8      11.9
              18.8      12.5:
              19.7      12.4
              20.7      12.3
              20.8      12.0
              21.7      12.3
              22.8      12.4
         Dec.  3.8      14.0:
               4.7      14.0:
               6.7     [14.0
               7.9      14.1
               8.7     [14.0
              10.7     [14.0

    The long duration of the outburst and possible presence of a fading
tail may suggest that the object may belong to WZ Sge-type dwarf novae.
