What tipped you off to > this one? Just curious!! Hi Ed and list, I thought my answer would be of interest for the list also. I simply checked the OIG Decay Prediction Report. This report lists all the objects about to decay with details on the prediction and the latest one or five elsets. Then I studied the orbit to look where the perigee was, because for a highly eccentric orbit the reentry point is always near the perigee. The BOZ motor is a reliable decayer in the sense that it has a predictable behavior compared with a satellite that has many appendages like solar panels. So I knew we had very good chances to see it decay over North America. I maintain a reentry section in my French web site (http://www.obsat.com/rentree.htm) that uses the predictions provided by Alan Pickup. When he's not available, I use the OIG predictions. This time I missed my first reentry by one orbit. The next pass (02:55 UTC) was too low to be observable from my place. I'm glad many on the list were able to watch this one.
