Mike has done so also, behind the scenes. I and Mike and Fred have spent some time trying to see the object, as the weather has permitted (not so much in the last few nights), and given the very wide-open possibilities as to its mean motion, etc. I want to emphasize that my points on July 16 (except for the last one, the shadow-entry point) are, I believe, much better quality than those on July 2. On July 2 I assumed I was seeing something that would be easily identified and so did not try to get precise points. The next night (i.e., July 3) I found myself puzzling about them, although as Mike and I have discussed, they probably were within five degrees of reality. (I might add maybe within two degrees.) On the other hand, I think that the first five July 16 points were fairly good. I tried them with Scott Campbell's Elfind program and got pretty comparable results with all ten pair combinations, although that program calculates a circular orbit, which of course does not fit this object. (For the July 2 points, Elfind gave wildly different results for the various combinations of pairs of positions.) It's very possible that tonight will be cloudy due to feeder bands from far-away Hurricane Emily (not so far from Paul in McAllen!). Later this week, under the full Moon, there may be fewer clouds.
