[Geysers] Beehive long cycles

[TSBryan at aol.com]

Yesterday in the UGB two different people asked me: "When will Beehive have 
its next episode of longer intervals?" The answer is September 22, at precisely 
05:43. Exactly, plus or minus about 2 1/2 days.

Seriously, I don't pretend to know what might be causing this cyclic 
behavior, but it clearly is real. It involves not only Beehive's intervals, but also 
other events, as shown below. Here is the pattern so far. (Two notes: 1. it is 
NOT possible to study these cycles prior to mid-April because the data 
(including electronic -- too many gaps) does not exist, and adata since then includes 
many electronic times; 2. the peak-peak intervals are given to the 1/1000 day 
(1.44 minutes) which is tighter than the accuracy of electronic times.

Note that all intervals, April 17 through September 11 morning, show an 
average of 15h 44m for 211 closed intervals.

The data is as follows:
Date and Time / Beehive Interval / Peak-Peak Interval / Observed Event
4/25/04 13:02 / 25h 45m / cannot determine / Giantess 4 days before
5/24/04 01:48 / 23h 37m / 28.532 days / none observed
6/20/04 11:01 / 22h 53m / 27.384 days / Giantess 5 days before
7/23/04 07:57 / 20h 29m / 32.872 days / Bronze 1 day before, Plume 1 day after
8/23/04 07:59 / 23h 08m / 31.001 days / Bronze 1 day before to 3 days after, 
Plume 6 days after

So there is it. Certainly, if anybody is aware of anything "really strange" 
on Geyser Hill on or about May 24, I'd obviously love to know about it... Stay 
tuned.
