[Geysers] Geyser report May 17

[TSBryan at aol.com]

Not much of a report, really. Unlike yesterday, the big geysers did not  
cooperate very well today -- Grand and Beehive, Lion ie on arrival, Oblong  a big 
steam cloud on arrival, and etc. The only good thing -- Artemisia's  eruption 
started when I was roughly 3 1/2 paces away from the edge of the trail.  That 
at 09:29 reinforces the thoughts of 12 hour intervals.
 
Anyhow, Grotto was in marathon all morning, and obviously had been in  
eruption for a very long time as of 07:00. It was still going at 13:00.
 
So I pulled some more closed interval numbers from the VC logbook for  May 1 
to today.
 
For Castle, I found difficulties in ferretting out the eruption types, but  
this is what I came up with. Normal intervals (14) average 13h 10m; Minor  
intervals (4) 7h 01m; post minor intervals (4) 14h 48m. This does not include  
today's minor.
 
As I suspected, Oblong has _really_ lengthened its intervals in the last  few 
days. Between May 1 and May 11, its average was 3h 46m (range 3h 19m to 4h  
00m). But starting with May 12, the closed intervals, in order, have been 3h  
54m, 4h 26m, 4h 36m, 5h 06m and 5h 13m; average 4h 39m. (Sorry, Julie.)
 
By the way, there have been no electronic download times for Castle and  
Grand since last week, due to the VC move, and today nearly all staff was  
involved in the move -- no rove except for the early geyser prediction  duty.
