Weird 500-mile-wide anomaly moves at an incredible speed over Canada seen on radar

On May 8, 2020 Mrmb333 noticed a huge radar anomaly and thought it was just a Dopler radar signature until he realized that it was over 500 miles wide moving from Northern Idaho into the Saskatchewan/Alberta border within a split second.


Given the incredible speed it jumped from South West to North East, it must have been something other than a flock of birds or a cloud of small pieces of aluminium, called chaff.

Although it remains unclear, could it be that the weather radar has reflected on something that came from space?
