Doesn't seem like the best of weather now in Iceland, hopefully it clears up. Otherwise it would suck for the people who have planned the trip months if not years in advance only to get a clouded sky, but that's always the risk with astrotravel.
Yes, we travelled to Cornwall in 1999 but it was cloudy. Got a marvellous view in Oregon in 2017 though. A friend of mine travels to all the solar eclipses he can wherever they are in the world. That's a bit too obsessive for me though. I'm in Devon this time but only 95% cover.
Currently in Keflavík, it is very wet, but I can see a pocket of blue sky in the clouds.
My trip coincides, I’ve been camping across the country and the rain has followed me across the whole island
It has been an incredible trip
Edit: it was rainy and cloudy but still so cool!
