UFO Lou ******MEGA STRUCTURE****** ’’APPEARS/VANISHES’’ 2 Minute duration.

Description - Melbourne, Australia - Never seen anything like this before. Object seems static. Simply appears, lasts a few minutes, then vanishes. Massive in size. Using a 50 mm lens. Orions belt in frame for scale. Can’t rule out the possibility of some kind of reflection? Recorded on my SD stick to minutes. Allow 10 - 15 seconds for intro & exit. Have normal speed upload if anyone interested.
