---------------------------------------------------------------------------- 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) Vent & Turban after C Continue Q Quit ---------------------------------------------------------------------------------------- Date Geyser Time Interval Duration Preplay Height Prediction 09/01/2002 Old Faithful 6:36 4:10 ? 136 09/01/2002 Old Faithful 8:11 1:35 4:24 7:59 120 8:10 09/01/2002 Old Faithful 9:56 1:45 4:05 9:35 130 9:45 09/01/2002 Old Faithful 11:19 1:23 1:47 none 120 11:30 09/01/2002 Old Faithful 12:24 1:05 4:35 12:20 110 12:24 09/01/2002 Old Faithful 14:05 1:41 4:25 13:53 115 13:58 09/01/2002 Old Faithful 15:41 1:36 4:16 15:36 136 15:39 09/01/2002 Old Faithful 17:19 1:38 3:39 17:10 130 17:15 09/01/2002 Old Faithful 18:47 1:28 4:07 18:46 110 18:53 09/01/2002 Old Faithful 20:22 1:35 4:18 20:21 130 20:21 09/01/2002 Artemisia 15:28 d=21m 09/01/2002 Aurum 9:36 09/01/2002 Aurum 18:54 09/01/2002 Bead 11:35 09/01/2002 Bead 12:04 09/01/2002 Bead 12:36 09/01/2002 Bead 13:08 09/01/2002 Beehive 1:34 ie 09/01/2002 Beehive 16:40 09/01/2002 Beehive's Indicator 16:20 09/01/2002 Box Spring 11:12 09/01/2002 Box Spring 11:49 09/01/2002 Box Spring 12:09 09/01/2002 Box Spring 12:37 09/01/2002 Castle 4:41 09/01/2002 Castle 17:13 09/01/2002 Daisy 6:38 09/01/2002 Daisy 9:38 09/01/2002 Daisy 12:29 09/01/2002 Daisy 14:46 09/01/2002 Daisy 16:54 09/01/2002 Fountain 8:30 ie end 8:55 09/01/2002 Fountain 13:56 09/01/2002 Fountain 19:01 d=24m 09/01/2002 Giant hot period 7:54 ie 3 SW vents 09/01/2002 Gizmo 16:57 09/01/2002 Grand 12:20 T2Q d=12m13s 09/01/2002 Great Fountain 10:00 p=0 of=86 d=47m 09/01/2002 Grotto 5:11 ie off ~ 5:25 09/01/2002 Grotto Fountain 9:20 09/01/2002 Labial 13:52 09/01/2002 Lion 7:01 initial 09/01/2002 Lion 16:04 initial 09/01/2002 Lion 17:35 09/01/2002 Little Cub 6:42 ie 09/01/2002 Little Cub 7:34 ie 09/01/2002 Little Cub 8:29 09/01/2002 Little Cub 9:28 ie 09/01/2002 Little Cub 10:18 ie 09/01/2002 Little Cub 14:37 ie 09/01/2002 Little Cub 15:29 ie 09/01/2002 Little Cub 16:19 ie 09/01/2002 Little Cub 17:12 09/01/2002 Little Cub 19:00 ie 09/01/2002 Lone Star 10:40 vr 09/01/2002 Narcissus 12:08 ie 09/01/2002 Oblong 5:03 ie 09/01/2002 Oblong 11:37 09/01/2002 Oblong 20:08 ie 09/01/2002 Pink 13:13 09/01/2002 Pink Cone 12:16 d=104m 09/01/2002 Plate 6:32 09/01/2002 Plate 8:53 09/01/2002 Plate 11:15 ie 09/01/2002 Plate 16:23 09/01/2002 Plate 18:54 09/01/2002 Plume 6:50 09/01/2002 Plume 7:31 09/01/2002 Plume 8:13
