Aircraft
While in level; smooth; night cruising flight; felt something similar to crossing a wake vortice but we were not near any other traffic. Observed right engine EPR and N1 were lower than left engines indications. Engine was under self-recovery when we observed engine thrust loss/reduction. While discussing the occurrence we received 3 or 4 calls from the cabin report observation of bright flash of light and flames from right engine. Completed engine thrust loss and engine failure checklists. Called dispatch on SATCOM. Conferred with Dispatch and Maintenance Control; reviewed options. Reviewed data from Boeing's computer and maintenance screens per advice of Maintenance Control Engine Controller and Engine Engineer; aircraft and all systems normal; continued to destination. Briefed relief crew prior to entering break period. Reviewed options. Remainder of flight uneventful.
In cruise flight crew noticed power loss on right engine and completed the appropriate checklist. All aircraft systems were operating normally. After conferring with Dispatch and Maintenance Control; crew continued to destination.
