I first detected this object in the course of my own survey on June 16 but mistook it for a variable. I even assigned a number for it in my own catalog of variables that I can detect with my equipment! I took numerous images when I first noticed it (waiting for it to move; hoping for a comet) but when it didn't, I catalogued it and moved on especially since it was visible (but much fainter) on previous images. Here is a list of prediscovery observations using an unfiltered 140mm f/2.8 telephoto lens + ST8.
