Fun! But the Canadian crater is Charlevoix. Still, it's not an L of a difference, is it?

ADMIN: Posts on the Chelyabinsk meteor event have been split into their own thread here.
Please continue the discussion there. For all other "the sky is falling" events, please continue as per normal

At least over the period observed, I only see rotation along a single axis. That would be somewhat rare, wouldn't it?

No, it's what we would expect from a fairly rapid rotator like this. But radar images are notoriously difficult to interpret so I would want to see more results of shape and rotation modelling before drawing any conclusions.
