We are usually used to seeing FORTE10 (one of the USAF Northrop Grumman RQ-4B “Global Hawk” based in Sigonella) carrying out missions over eastern Ukraine or over the Black Sea.
But in the last time the American drone carried out the usual mission off the Crimea but then continued eastwards.
After a surveillance flight over Georgia (not far from the borders with Armenia and Azerbaijan) is now making a similar (and usual) mission over eastern ukraine.
