Congratulations Paul. Nice results under difficult circumstances.
I was also in China north of Hangzhou on Qiantang River Tidal Bore observation site with approx 1000 others.
Sadly, clouds persisted through the entire event and actually thickened around totality. Did see a hint of exit diamond ring through a brief chink in the clouds. Magical event, though, and extremely memorable. The fade in light in the seconds to totality gave me goosebumps. Managed to catch some partials through cloud before and after totality. Stayed on to observe the world-famous tidal bore that raced past an hour and a half after 4th contact.
Cheers.
Russ.
