The latest elset for this decayer ...

Iridm 19 Delta r 5.9  2.4  0.0  5.6 d            212 x 176 km

... is 11 seconds late against the SatEvo "9270" evolution I posted
yesterday. The predicted decay continues to slip and now stands at April
17.94 +-0.25d. Given the recent trend, I would not be surprised to see
the decay slip into April 18 UTC.
