As I said earlier, probably a rocket body reentry...
Could it be the CZ-4B (Long March 4) reentry, that was predicted in late 23th, early 24th ?

Re-entry of 2014-088B / 40363m -- It was stage 3 of the CZ-4B rocket that launched Yaogan Weixing 26 on Dec 27, 2014.

The bright bacground spots on these images, which look like stars, do not seem to correspond to each other from frame to frame. Are those star images or CCD-like pixel noise?
The lens was a Rokinon 24 mm at f1.4. There should be no hot pixels in the shot. Since I used the in camera noise reduction. The shots were only 5 seconds at ISO 3200. This camera does good even at ISO 12800.
