[Aztlan] repeat transits of Venus

[martha noyes]

Aloha - anyone know at what intervals transits of Venus can/could have been seen from a single location?  For instance, if a transit was visible in Hawaii in 910 AD, when would it be visible again or when would it have been visible years earlier?  

Mahalo for any help on this.

Oh, I lost an email from someone on the list who asked for references to materials available in both Hawaiian and English.  If you'll email me again, I can send you some references.
