The Iridium Delta 2 was running 22 seconds late on yesterday's
prediction at the epoch of the latest elset from OIG:
Iridm 45 Delta r 5.9 2.4 0.0 5.6 d 155 x 142 km
1 25109U 97082F 98174.77456654 .13039629 -14508-5 26066-3 0 3079

I predict decay for June 23.92 (22.00 UTC, just about now) and the
following final elset
