---------------------------------------------------------------------------- A Note on Intervals: Intervals have been computed in cases where observations are for consecutive eruptions. In cases where observations are not known to be consecutive, intervals have not been computed. Intervals computed when both observations were "ie" are noted with a preceding * (e.g. *2:16). ---------------------------------------------------------------------------- Geyser Log abbreviations ie in eruption (wasn't observed at start) d duration I interval h height 3h45m15s "3 hours, 45 minutes, 15 seconds (for instance)" > greater than < less than ns "near start (the top of a steam column is observed still rising--when in doubt, ie is use d)" ini "initial-used for Lion, for instance" MJR major min minor ind indicator-used for Beehive vr "Visitor Report-it can be logged, (a reliable report) but the time might not be accurate" B "bursts as in Grand or Plume, recorded for instance as 3B" of overflow p "pause, time between 1 meter boil and burst from Great Fountain" Grand Eruption Codes: Interval type Dn Grand erupted n Turbans after long interval D0 Grand erupted on long Turban interval N No long Turban interval observed Starting Geyser T Turban G Grand Bursts n n bursts n+m n bursts plus m afterbursts * long 2nd burst (d >1m15s) # long 3rd brust (d >1m15s) C Continue Q Quit ---------------------------------------------------------------------------------------- Time Interval Duration Preplay Height Prediction 01/01/00 Old Faithful 1:13 1:30 ~4:10 1:03 1:08 01/01/00 Old Faithful 8:30 ~4:10 8:15 01/01/00 Old Faithful 9:51 1:21 ~4:!5 9:39 148 9:56 01/01/00 Old Faithful 11:15 1:24 L 11:14 --- 11:19 01/01/00 Old Faithful 12:41 1:26 ~3:50 12:31 120 12:41 01/01/00 Old Faithful 14:17 1:36 4:00 14:05 ~160 13:59 01/01/00 Old Faithful 15:45 1:28 4:18 15:38 135 15:39 01/01/00 Old Faithful 17:04 ie < =1:19 17:14 01/01/00 Aurum 9:30 01/01/00 Aurum 12:07 2:37 01/01/00 Beehive 11:28 d=5m1s 01/01/00 Beehive's Indicator 11:15 ie 01/01/00 Castle 14:06 01/01/00 Daisy 8:51 01/01/00 Daisy 10:52 2:01 01/01/00 Daisy 12:48 ns ~1:56 01/01/00 Dome 12:10 ie 01/01/00 Fountain ~13:00 ievr 01/01/00 Grand 16:14 vr 01/01/00 Grotto 8:40 ie still ie 14:30 01/01/00 Lion 13:28 ie 01/01/00 Lion 14:51 ie 01/01/00 Little Cub 8:13 ie 01/01/00 Little Cub 10:11 >=1:58 10:12 ie 01/01/00 Little Cub 12:10 1:59 12:20ie 01/01/00 Little Cub 14:08 ie < =1:58 01/01/00 Little Cub 16:10 ie *2:02 01/01/00 Lone Star 13:38 vr 01/01/00 Plate 10:34 01/01/00 Plate 13:38 ie < =3:14 01/01/00 Plume 8:24 01/01/00 Plume 9:11 0:47 01/01/00 Plume 10:04 0:53 01/01/00 Plume 10:55 0:51 01/01/00 Plume 11:46 0:51 01/01/00 Plume 12:40 0:54 01/01/00 Plume 14:18 01/01/00 Plume 15:06 0:48 01/01/00 Riverside 10:58
