[Geysers] Geyser report April 27 and 28

[TSBryan at aol.com]

Apparently there was never any gazer in the geyser basins yesterday 
(Wednesday, April 27) and a naturalist only for the early prediction and download duty. 
There was almost nothing for the day in the logbook. Today started out 
cloudy. When the sun came out the wind died down some. By around 1100 there was 
hardly a cloud in the sky, but now at 1345 the temperature in West is only 36.

On Tuesday, 4/26, Grand had been at 0708e. the next was at 1614, giving an 
interval of 9h 06m. As had happened the day before, that interval had been 
"rifted."

Overnight to Wednesday, Grand was at 0001e (I = 7h 47m) and at 0631e (I = 6h 
30m). Additional times for yesterday were not available this morning. Today 
(Thursday) Grand was at 0415e. At 1050 Rift started erupting. Based on the past 
days experiences, when Grand failed to erupt on the first Turban after Rift, I 
left. And so the stupid thing erupted on the next Turban, at 1114. I = 6h 59m.

Tuesday's Beehive had been at 1114 (yes, 1114 again), yesterday's at 1513. 
That's 27h 59m for what we hope is a double interval. This morning, Beehive 
clearly had gone in the night.

So did Fan and Mortar, finally. My guess based on the complete lack of any 
recovery is that the eruption occurred at least as late as 0200, probably later, 
giving an interval somewhere in the approximate range of 8 1/2 to 10 1/2 days.

Grotto ended a marathon not too long before my arrival, which was at about 
0830.

I saw Link erupt to maybe 4 feet, certainly bigger than a "normal" minor 
eruption.

I haven't paid them a whole lot of attention, but both Anemones are active. 
I've recorded intervals on Big Anemone everywhere from 14 to 21 minutes.

Every time I've been up around Sponge, quietly standing water has been 
visible in Plate, Boardwalk, Park Place and others (I did see a few bubbles in Plate 
a few days ago).

Silex has not been active since early Tuesday.

Fountain had erupted sometime before 0730 today, and I'm quite certain it had 
not gone again as of 1240, when its formations and runoff, Super Frying Pan, 
Twig, Jet, and Spasm were all bone-dry.

On the aside, I am back early today because the copy edited manuscript of my 
revised and expanded "Geysers: What They Are and How They Work" is in hand, 
and so I got work to do. The editor hopes to have it ready to go to press by the 
first of June. Pat -- your Beehive will be the cover; Alan -- your Tation 
T-25 will be inside.... Also, I will not be in the Park tomorrow as I need to be 
here to receive a FedEx shipment.
