500 Mile Wide ‘Mothership’ Anomaly Spotted on Radar

A mind-blowingly massive radar signature was picked up radar on May 8, 2020

Mrmb333 noticed the huge anomaly and thought it was just a random Dopler radar loop until he realized how big it was (over 500 miles wide), he also notes whatever it was moved from southwest to northeast (Northern Idaho into the Saskatchewan/Alberta border) within a second.

Considering the fantastic speed it moved from South West to North East, it rules out natural explanations such as a large flock of birds or a cloud of small pieces of aluminium, called chaff.

Any idea as what this might be? Alien mothership (UFO)?

The source or cause of this incredible anomaly remains unknown at the present time.
