This fireball was with a high degree of certainty the re-entry of a Russian Soyuz 3rd stage, #39083 (2013-007B), the 3rd stage from the Soyuz that launched the Progress cargoship Progress-M 18M towards the ISS on February 11th.
USSTRATCOM issued a TIP message indicating decay at 21:15 +/- 1 m UTC near 49N, 13 E.
Below is a quick map (made using Orbitron) of the trajectory and approximate position of the re-entry.

Time, general description and reentry data all fit quite well.
