Please help me explain why that is wrong.
Thanks

Basically, being above the Arctic Circle doesn't affect how fast the moon passes by the earth. The moon is orbiting the whole earth, not just part of it.
The duration of this one in northern Greenland is about 2 minutes. I am curious about where the claim of 30 minutes came from.

We were having Afternoon Tea on the Discovery Princess talking about future eclipses. I didn’t want to be rude so I just finished up and said I was taking a nap.

C1 to C4, instead of C2 to C3?
(Disclaimer: I'm thinking aloud and too lazy to look up the actual times. Sorry. )

Well, actually totality will last around 45 minutes north of the arctic circle in 2026. The umbra first touches the Earth in north Siberia at around 16:59 UT August 12th. The umbra then crosses the arctic circle moving south just NW of Iceland at around 17:44 UT.
Probably not what was meant, though.

For the one fixed location 7min and 32sec is a theoretical limit for longest possible total solar eclipse. As far as I recall the longest one in recorded history happened at year 743BC and lasted 7min 27sec.
