Okay, here's a explanatory follow-up and an apology to all. I received a report that an object was seen flashing at about 10:45 UTC on October 28, with a sky location indicated on a sky image. Findsat said the best candidate was ETS 6, and Highfly gave predictions for a matching RA and Dec (not far southwest of Procyon) at that time. But then I received follow-up indicating that Heavensat and Orbitron put ETS 6 at a very different RA and Dec than where Highfly said. It turns out that this other position was where ETS 6 was at 11:45 UTC instead of 10:45 UTC. So, this would appear to be a case of a one-hour time-zone conversion error by a user rather than programs producing different predictions. So I owe everyone -- especially the programmers of the two programs! -- an apology for raising the issue of possible program prediction errors by Heavensat and Orbitron where there were none. It does seem that what Mike wrote about the Heavensat display possibly being confusing could still be a consideration. But again, I was not meaning to criticize but just to point out the possibility that some people might be missing objects they wanted to see. Clearly most programs are designed primarily for LEOs, which are only for the sky for a few minutes, not for many hours like high-altitude objects are.
