I would like to add a few Z Cam candidates to the AAVSOnet observing queue. UY Pup appears to be in a standstill right now. This would be the first historical standstill, so I am requesting nightly observations in V and B commence immediately and continue indefinitely until we nail down all the properties of the system (Type, period, range of variability, etc.) precisely enough to write a paper for JAAVSO.
V1363 Cyg is an unusual CV that has never shown standstill behavior, but may be related to Z Cams and hibernating novae due to the presence of a nova shell as reported in Sahman et al 2015 (http://arxiv.org/pdf/1505.06048v1.pdf). I am requesting nightly observations in V and B.
NSV 14581 is another interesting Z Cam candidate, as well as an eclipsing system. It's orbital period and outburst recurrence time match the typical Z Cam range, but no standstills have yet been observed (http://arxiv.org/pdf/1201.6556v1.pdf). I am aware that at 82 degrees north it will be difficult or impossible to observe on some AAVSOnet telescopes. I am requesting nightly observations in V and B.
