  IW And was discovered as a unique blue variable, which spends 72% of time in
"inactive" state, and was only occasionally observed in bright or faint states.
Although the past spectroscopy confirmed that the object is a cataclysmic
variable (CV), the object has been regarded as significantly different from the
known subclasses of CVs. We observed IW And on 55 nights between 2001 December
6 and 2002 March 25. These observations clearly indicate that the object is a Z
Cam-type dwarf nova. The duty cycle of standstill in IW And is exceptionally
high among Z Cam stars. IW And is apparently the first object to fill the gap
between classical Z Cam stars and novalike (NL) stars.
