Help with airline and registration

I just found this picture taken at Uytash Airport, seemingly looking over the apron.
I know that the two Tu-134s and one of the Tu-154s near the camera is from SouthEast Airlines and the other 154 is from Daghestan Airlines. The regsitration i would like some help with is the Tu-154 in the background. I have never seen another Tu-154 in that livery and would very much like to see what airline it is and what the livery looks like up close.
Thanks in advance.
