[Geysers] Giant and other May 19

[TSBryan at aol.com]

GIANT May 19, 2007 @1209, interval exactly 5d 00h 00m, duration somewhat  
short @86 minutes.
No doubt you all already know that Giant erupted today. Here are a few  facts.
 
The Grotto marathon that started between 1700 and 1800 (apparently) on  
Thursday continued throughout yesterday. Kendall Madsen checked it last night  and 
found that it was still 2145ie but off before 2320. Assuming roughly 2230  
off, that was a marathon duration of about 29 hours. Nice timing.
 
So add 9 hours and you get 0730. We were there. Waiting. And waiting. The  
big event finally began at 1156, so a recovery period of about 13 1/2 hours.  
Bijou showed good water (as opposed to slight spitting) about 20 minutes before  
the hot period began.
 
1156 water rising in Mastiff, quite quickly.
1157 Feather on; Feather Satellite on only 24 seconds later; Mastiff  
overflowing heavily with surging 2 to 3 feet.
approx 1204 after continuous surging, Mastiff flat but still overflowing  
strongly, then after not more than 30 seconds, surging again. This time the  
surging was several feet high and wide.
1206 Mastiff climbing 10 -- 20 -- 30 -- etc. feet. Although I barely saw it  
as I dashed for a hoped-for good photo spot, Mastiff reached at least 50 feet  
accompanied by a roaring Catfish.
1209 Giant.
 
It was not a particularly good photo op day, given considerable cloud cover  
and lousy light. But OK. Three in a row for me. Attached is a photo that sort 
of  shows Mastiff just as Giant was rising.
 
Open question: is this sort of duration typical of a Mastiff function  
eruption?
 
BEEHIVE is item #2. No eruption today, and the bubblers were active as  
before, really as if there was no eruption yesterday. However, per Karen Lowe, a  
long-time, experienced Xanterra employee reported seeing Beehive in eruption on 
 the evening of either Tuesday 5/15 or Wednesday 5/16 (Karen wasn't sure 
which)  at about 2000. I know some of you are archiving Webcam shots. Does anybody 
see  Beehive at one of the suspect times?
