[Geysers] North Goggles data on GOSA web site

[Michael Goldberg]

While I don't have notes handy to be certain, I am fairly confident that 
there was continuous overnight observation on 6/29-30/2000, and 
the activity consisted of North Goggles and Lion alternating several 
shorter series of eruptions.
