---------------------------------------------------------------------------- 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 02/11/00 Old Faithful 8:07 cam 02/11/00 Old Faithful 9:35 1:28 4:18 9:30 136 9:20 02/11/00 Old Faithful 11:07 1:32 4:06 10:56 140 10:50 02/11/00 Old Faithful 12:10 1:03 4:10 --- 148 12:20 02/11/00 Old Faithful 13:32 1:22 4:23 13:31 140 13:36 02/11/00 Old Faithful 15:00 1:28 4:10 14:50 140 14:55 02/11/00 Old Faithful 16:28 1:28 4:23 16:19 140 16:25 02/11/00 Aurum 13:19 02/11/00 Beehive 10:48 ie 02/11/00 Castle 12:45 ie 02/11/00 Daisy 11:12 02/11/00 Daisy 13:31 2:19 02/11/00 Fountain 8:08 ie 02/11/00 Grand 10:17 2C 02/11/00 Grotto 11:12 ie marathon 02/11/00 Lion 12:41 ie 02/11/00 Plate 10:35 02/11/00 Plate 12:21 ie < =1:46 02/11/00 Plate 13:43 ie *1:22 02/11/00 Plume 10:57 02/11/00 Plume 12:06 1:09 02/11/00 Plume 13:31 1:25 02/11/00 Rift 9:34 ie end 10:17 02/11/00 Riverside 13:19 02/11/00 Seismic Satellite 12:05 d=6 h=5 02/11/00 Seismic Satellite 12:28 0:23 d=6 h=8 02/12/00 Old Faithful 8:32 L 02/12/00 Old Faithful 10:02 1:30 4:05 9:56 136+ 9:57 02/12/00 Old Faithful 11:26 1:24 4:10 11:18 136+ 11:26 02/12/00 Old Faithful 12:57 1:31 4:18 12:47 160 12:52 02/12/00 Old Faithful 14:35 1:38 4:10 14:16 150 14:20 02/12/00 Old Faithful 16:03 1:28 4:26 --- 148 15:55 02/12/00 Aurum 10:20 02/12/00 Aurum 12:06 1:46 02/12/00 Aurum 14:36 2:30 02/12/00 Beehive 14:08 02/12/00 Beehive's Indicator 13:56 02/12/00 Castle 12:47 02/12/00 Daisy 10:29 02/12/00 Daisy 12:23 1:54 02/12/00 Daisy 14:20 ie 1:57 02/12/00 Depression 11:20 02/12/00 Dome 12:41 ie initial 02/12/00 Grand 10:08 T2Q 02/12/00 Great Fountain 14:19 ievr 02/12/00 Lion 12:43 02/12/00 Lion 14:09 1:26 d~30s 02/12/00 Lion 14:18 0:09 d=3 02/12/00 Little Cub 9:10 ie 02/12/00 Little Cub 14:07 ie 02/12/00 Plate 13:53 02/12/00 Plate 14:31 0:38 02/12/00 Plate 16:03 1:32 02/12/00 Plume 12:26 02/12/00 Plume 13:08 0:42 02/12/00 Plume 14:29 02/12/00 Plume 16:30 02/12/00 Sawmill 9:02 ie 02/12/00 Sawmill 11:17 02/12/00 Sawmill 11:33 0:16 02/12/00 Sawmill 11:53 ie < =0:20 02/12/00 Sawmill 13:48 02/12/00 Uncertain 13:01 ie 02/12/00 West Triplet 9:26 d~38m 02/13/00 Old Faithful 8:12 ie L 02/13/00 Old Faithful 9:44 < =1:32 4:15 9:29 136+ 9:35 02/13/00 Old Faithful 11:17 1:33 4:13 10:53 125 11:11 02/13/00 Old Faithful 12:42 1:25 4:09 12:35 snow 12:44 02/13/00 Old Faithful 14:16 1:34 4:08 14:02 130 14:08 02/13/00 Old Faithful 15:46 1:30 4:03 15:38 >136 15:41 02/13/00 Old Faithful 17:12 1:26 4:02 17:02 17:09 02/13/00 Aurum 9:27 02/13/00 Aurum 12:17 2:50 02/13/00 Aurum 15:00 2:43 02/13/00 Beehive 9:01 02/13/00 Beehive's Indicator 8:46 02/13/00 Castle 13:07 ie steam 02/13/00 Depression 13:17 ns 02/13/00 Dome 9:27 still active 02/13/00 Giant hot period 9:59 ie bathtub 02/13/00 Grand 8:55 ie >=2Q 02/13/00 Great Fountain 17:25 ie 02/13/00 Grotto 9:01 ie end ~09:50 02/13/00 Lion 10:13 ie ini 02/13/00 Lion 11:31 >=1:18 02/13/00 Lion 17:11 ns >=6:58 ini;
