Disk over Potters Bar, HERTFORD · United Kingdom

The report, as filed

Whilst waiting at the west bound bus stop 100yds south of tescos supermarket i was looking east up road for the next bus looking up about 30 degrees i saw a thin Grey wobbling disk i at around 500 to 1000 ft traveling at around 30MPH going north east towards Potters bar rail station. the sky had lighter grey 100% low cloud cover under 1000ft and the disk skimmed along the bottom of the cloud. The disk was i would estimate 50 to 100ft in diameter but very thin and flat maybe only 1 or 2 ft thick, wobbing like a plate spun on a stick about to fall off With what i would describe as 6 to 10 modules around its edge, randomly, Half circle, Square, Triangle and Rectangle. I was able to get a good look at its thickness and shapes around it's edge as the slow wobble ran around plus and minus 40 degrees from the horizontal. Its slow Wobble had no effect on its direction of travel or constant speed which was in a straight line along the bottom of the cloud. Looking like the inverted picture of a ship on the sea
