A week ago, I was under the impression that I would see this object one hour later than those in California. I based that on the MISTAKEN thought that the satellite appeared about 15 degrees farther west for me than for those in CA. That was due to a confusion while playing with visibilities for the two sites at different local times. I just reran Skymap and found that at the same UT, the difference in position is only about 0.1 degree. Thus the times we see the flashing will be the same - when using UT! However, I still think that we should see about a 3.6 minute difference in time of max brightness from one day to the next. The times should become later assuming a 1.9 degree westward longitude shift per day and the earths approximate 1 degree per day motion eastward in its orbit. Over the course of a week, that would be about 25 minutes. This does not consider any effect of the sun's changing declination. Ron Lee
