Progress M-27M reentry.

The final time of reentry is 8 May 2015 at 02:20 UTC (04:20 CEST), with an accuracy of plus or minus 1 minute.
This corresponds to an altitude of around 80 km (so, roughly, 10 minutes from touch down). This would have been the point in time where the re-entering object was the hottest and so observable from space. This time also corresponds to a location of 51 Degrees South latitude and 273 Degrees East longitude, over the ocean west of the southern tip of the coast of Chile.
