Su-35 BVR HUD video against Ukrainian MiG-29
Engagement (apparently) happened during June.
The heading indicator shows the pilot and the ASC(Active Steering Cue - when pointed in the direction of the ASC, the missile has the best chance to reach the target) cue -- the circle -- pointing towards the South, so it is possible that the engagement took place somewhere parallel from the Belgorod to Kharkiv vector.
The pilot also cranks to the left after the missile deployment to the East, which is towards to the Russian territory if this happened over Belgorod - Kharkiv.
The pilot fired 3 R-77-1 Adders on a single target at 60km(32-33 nautical miles).
