I'm not sure of the observability of the star against the Umbra but I'll find out...
Dave,

I think the graze you are referring to in eastern AU occurs at about 6am -
  • 30 mins into totality,
  • Moon altitude 12 degrees
  • 1 hr until moonset
  • 4 mins before the start of nautical twilight ACT, maybe about 10 mins after the start of nautical twilight on the coast.
Background sky brightness, atmospheric instability, low altitude extinction not to mention the rain that's predicted along the graze path, will further complicate observations. It passes 10k from my dark sky site but I don't think it's a goer. I'll probably stay in Canberra.

cheers

Joe
