I feel that this is interesting enough to post here.

In other words, this SU UMa star with an orbital period of less than
2 hours has been performing a Z Cam like standstill at V~15.7 ongoing
since July 20th.  I'm not very familiar with the theory behind Z Cam
type standstills, but this seems unusual to me.  Can anyone comment on
this?
 
A confirmation from someone else besides me that this is really what's
happening would also be nice, I think.
