Orange defined circle with interior slow burn flame passes slowly E to W following Glen Creek above tree canopy Watkins Glen, NY.Looking up through trees of campsite, (Tuscarora Village N. side) Watkins Glen State Park, husband and wife observed orange red circle moving silently slowly in west direction up Glen Creek (East to West). The object was orange in center and had a red fire like ring on the peripheral circle, which had fire like licks or prongs emanating into the center orange portion, similar to looking straight up into the base of a rocket outlet, but flame going inwards to center and flames were slowly intermittent like a dying ember not a fast burn. The object moved slowly west (visible intermittently through the tree canopy) and did not appear to be relatively high, I.E. lower than commercial jet aircraft and about as high as local prop aircraft). The shape was definite perfect circle not rough like mold burn. Lost track through tree canopy.
