It looks like Z Cam has come out of standstill.
Indeed it has - after around 200 days...
May 22.934 UT 13.0
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.
