Ask HN: Detailed, realtime satellite imagery, to verify convoy length?

There's a convoy of trucks heading for Ottawa in Ontario, Canada. News sources say it's on the order of a thousand trucks; social media says there's over 50 000 trucks, and that it stretches on for 400km.

I was wondering if there is a way to verify either of the claims. Is there a way I can see detailed satellite imagery with images from today?
