[Geysers] Grand intervals/wait times

[Ralph Taylor]

Currently (as of last Saturday) the predicted interval is 8 hours plus or
minus two.  For the past month 97% of the eruptions occurred within that
window.  The remaining 	4.5% were after the window.

I post these stats weekly at 
http://www.gosa.org/electronicsummary.aspx

The Grand stats are at

Last I knew, Grand's eruption was bound to occur plus/minus two hours of
prediction time.  Is that still the same?  And how often does it erupt these
days?  About once every ten hours?

Thanks,

Lucille Reilly
