[vsnet-outburst 8019] EF Tuc bright

[Taichi Kato]

   According to Alan Plummer (via AVSON), the cataclysmic variable
EF Tuc (= EC 23593-6724) is bright (was bright a month ago??).

   ASAS-3 data show maxima of similar brightness about once per year.
For example, the 2001 July maximum reached V=12.27.  The light curve,
however, looks like that of a Mira-type variable(!?).  The object
was also recorded bright in 2005-2006.  On 2005 Oct 4, ASAS-3 recorded
V=12.84 (V=14.23 on Sep 30) and the object faded slowly after that.
The object stayed more constant around V=13 in 2006 May and June.
The light variation looks very atypical for a dwarf nova or a usual
NL-type variable.  I wonder what is the nature of the object, or
am I looking at a different object on ASAS-3?
