Finally got to observe this a few minutes ago on a nice 65 degrees elevation pass with only a small amount of cloud about. In view of my latitude this is of considerable interest to me! Not able to make precise positional observations but it was a reasonably steady mag 1, did not appear to reach anywhere near the -2.6 predicted by Orbitron. I estimate culmination at 08:32:01 UTC, my timer was precise (handheld GPS) but my observation may not be. So latest TLE is definitely close to the mark, not likely to be more than 15 seconds out. Correct me if I am wrong but with a 39 degree inclination, and the fact that the shuttle passes over here when it heads for California, it seems to me possible that the deorbit burn of 36514 could take place near here? (whether or not it will happen when visible of course is another story!)
