[Geysers] Another dual 7/23/13

[Tara Cross]

The known Fountain/Morning duals are listed below (time listed is the start of Morning):

June 5 @ 1744
June 13 @ 1632 ("Trifecta")
June 24 @ 1446
July 7 @ 1007
July 16 @ 1721
July 22 @ 0911
July 23 @ 1846

As you can see, the duals have not been "fairly regular" so there is no way to guess when the next dual will be.  If you are serious about seeing Morning, your best bet is to be in the area for each window of opportunity.  So far, *most* eruptions have occurred between 8.5 and 10.5 hours after the previous Fountain eruption, and the longer duration of Fountain, the better the chance there is for Morning.  Whether it will be a dual or not is entirely up to the geysers.

Recently, Scott Bryan attached a graph of the Fountain Morning dual occurrences. From the graph, the interval between the duals is fairly regular.  (I’m sure there is a way to express “fairly regular” with a more formal expression to demonstrate the uncertainty.)   With this on July 23rd, is it possible to guess when the next dual would be?  I’d like to try and observe one. S. Ott From: geysers-bounces at lists.wallawalla.edu [mailto:geysers-bounces at lists.wallawalla.edu] On Behalf Of Tara Cross

Subject: [Geysers] Another dual 7/23/13 Quick report:

Fountain 0913 d=34

Then,

Fountain 1846 d=63.5 minutes
Morning 1846 d=20m25s

With the shorter Fountain duration we were not expecting to get Morning but the boiling in the pool got stronger and stronger as the eruption neared, and Morning started about 20 seconds after Fountain.

So now we are not "safe" after a duration of less than 37 minutes.

More details later hopefully.
