AY Psc is an eclipsing Z Cam-type star!
According to AAS 201 (40.07), AY Psc is found to be (probably the first,
except the rather atypical EM Cyg) eclipsing Z Cam-type dwarf nova!
Please observe this object closely (on nightly basis, as in other DNe),
and regularly monitor the eclipses. Catching the ingress and egress phases
of standstills is extremely important (when such a phase is suspected,
please use vsnet-alert to announce the detection) in testing the theories
of standstills.
Since the object is currently favorably situated, please start monitoring
the long-term behavior and for state changes right now!
