[Geysers] What is Grand's Shortest Interval?

[Graham Meech]

Jeff - the entry on geysertimes.org on 7 October was 1959 Electronic, not a
visual sighting.   One reported electronic time while I was in the park was
off "real time" by 9 minutes.   So on 7 October the sensor could have been
off by 2 minutes.

 

Back on 28 September 2012, Maureen reported Grand eruptions at 0950 and
1450, so they were 5 hours 0 minutes apart and observed by the same person.
This is the shortest reported interval on geysertimes.org this season.

What is the shortest interval of Grand ever noted?

I have one candidate, as follows:

07 October 2012
Grand 1459
Grand 2001, I = 5 hours 2 minutes

The geysertimes record shows the second eruption occurring at 1959, which
would make a 5 hour interval exactly.  However, I cannot reconcile the 2
minute difference between this time and my own observation, as I was passing
Belgian Pool when Grand began.
