   It would be worth noting the remarkably long duration of the
outburst and a relatively small tendency of fading.
Although the former and the amplitude and superhump period
suggest a WZ Sge-type object, the apparent constancy nearly for
a month is unusual.  There may have been a missed brighter
maximum shortly after the initial detection.  Inspections of
survey photographs or CCD images would be helpful in clarifying
the evolution of this unusual object.
