It looks like Z Cam has come out of standstill.

Z Cam back?

Is Z Cam back in standstill, or is the start of the first outburst after standstill. I had it last night (May 23) at 22.34 UT as an object of 11.8. Interesting

It is indeed interesting.  If it hadn't been for a couple of observations on May 22/23 showing Z Cam had faded to minimum, it would appear that the standstill hadn't ended at all -  or indeed if Z Cam is now brightening to outburst, it would seem that the outburst had begun from standstill!  I'm still not 100% convinced that the latter happens at all, and won't be I don't think until I see continuous photometry proving it.
