[Geysers] Geyser report April 30

[TSBryan at aol.com]

A good long day in the park today, and a whole lot more fun! I though  
something was to be posted about this mornings Giant recovery (no eruption), but  
apparently not... So I start with that.
 
The Grotto marathon that started about 1830 on Saturday, 4/28, did not end  
until something around 2010 last evening. The recovery hot period finally  
occurred a bit before 0700 today. I was not htere, so this info is from Andrew  
Bunning via Karen Low. The hot period evidently lasted about 15 minutes and  
involved Mastiff suring as high as 6 feet. But again, no Giant.
 
Subsequent hot periods took place at 0951 (d<4 min), probably about 1230  
(really strong Bijou) and 1415ie (weak, d~3 min). It is certain that no hot  
periods were missed during this time.
 
Riverside was 0836 and 1443ie.
 
Artemisia was at 14xx yesterday, 1408ie today.
 
Daisy pulled a bit of a surprise today, 0911 and then not until 1234, 3h  23m 
on a day with rather little wind.
 
Oblong was 0847 and 1426, definitely a single interval and the 1426  eruption 
by far the weakest I've seen this year, small and with a total duration  of 
not more than 5 minutes.
 
At some point I'll be posting separately a list of Grand's intervals ince  
opening. Short. I've done no calculation yet, but I'll bet the average interval  
is only about 7 1/2 hours. Today Grand was 0511 (thanks Andrew) and 1149ie 
(not  longer than 6h 38m, -1Q).
 
Castle had had a minor yesterday afternoon, then apparently a rather short  
(~3 hour ? ) interval to the major. Today, major ie water at 0749.
 
Plume 1141, 1231, 1325, and 1414.
 
Aurum was never called. Did not see Depression. Lion was in the logbook for  
060x ie, and was splashing a little bit around 1300.
 
Tilt was having occasional overflows from a full crater, and sometimes  (only 
sometimes) it drained at least some afterwards. But no eruption was seen  
until Karen and Andrew saw it last evening. Then today, literally as Barry Leedy  
and I were talking about it, it erupted at 1327. None of it was higher than 1 
to  2 feet, but at least it _is_ active.
 
And I guess that's it for now.
