It is called AVRORA it seems to always be located in the vicinity of 50.7795 N 50.7795 E at exactly 10005 m or 32,000 ft. It is stationary. Says Invalid transponder code. It is located right in the lane that it seems like a bunch of freighters fly in the ANC to Tokyo / Seoul route. In fact an Atlas Air 747 few right on top of it this morning. Does anybody have an idea what this could be or can you help me find someone who would know? Thanks Andy

AVRORA is a surveillance radar. If you watch aircraft flying by they turn from blue to yellow, meaning they have transitioned from satellite based data to ground based. I suspect the “aircraft” you see is some sort of glitch showing the “corner” of the ground based radar’s range.
