That was followed by a Turban Delay Interval, one where the heavy runoff didn't start until the 30 minute mark. The interval was so long that Rift started during the Turban eruption.<\/p>\n\n\n\n<p>The West Triplet eruption lasted almost exactly an hour, and about a half hour later, Grand filled nicely on a long Turban eruption interval that resulted in a One Burst Eruption.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">2026-Sep-11 : 08:50:53 D3\/G1Q\n\n 08:50:51\tBoop\t-0m02s\n 08:50:53\tB1\t--- d=10m42s\n 08:50:54\tVent Ovfl\t0m01s\n 08:51:05\tTurban\t0m12s\n 08:54:13\tVent\t3m20s\n 09:01:35\tP1\t10m42s\n 09:02:29\tV&amp;T Quit\t11m36s\n\n\t\t\t\t     \t\u03a3D=10m42s\n\t* * * * *\n 07:13:20\t\t\td=04m22s\t\n 07:17:12\tWest Triplet\n 07:50:30\tInt: 37m10s\td=04m55s D0\t\n 07:54:07\tRift\n 08:09:19\tInt: 18m49s\td=02m30s D1\t\n 08:28:56\tInt: 19m37s\td=04m07s D2\t\n\t\t      Grand: 21m57s<\/pre>\n\n\n\n<p>Tried to wait for Beehive after that, but it was so windy and miserable that most of the people waited decided to let someone else stay there. Which was why it appears that no one actually saw the start of the eruption of the Indicator, as everyone had left. The Beehive eruption was still nice, despite the wind.<\/p>\n\n\n\n<p>At that point, there wasn't much to do around the basin, which meant it was a good day to take care of various housekeeping chores which had been postponed due to the waiting in the Bijou Cage.<\/p>\n\n\n\n<p>Got back out to Grand just after the six hour mark. Immediately got a Turban Delay Interval eruption, which meant it was going to be a bit of a wait. Seven turban eruption intervals later, we got a second Delay Interval. By that time, it was getting stormy to the north, and the wind was making the whole wait as miserable as one on Geyser Hill. By this time, it had been over three hours without any activity from West Triplet. An hour later West Triplet started to erupt, but finished within a couple of minutes.<\/p>\n\n\n\n<p>That seems to have been sufficient activity to qualify for the opening of the West Triplet window, as Grand finally erupted 20 minutes later. Grand's pool was full and having waves at the 13 minute mark when Turban started. Turban started out slow, then suddenly began acting like it does when Grand erupts. The second burst consisted of over two minutes of some of the smallest Big Sawmill activity I've seen in quite a while. Grand repeatedly looked like it was stopping, only to boil up a few meters high, then have some small jets.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">2026-Sep-11 : 19:17:53 D7\/D5\/T2*Q\n\n 19:17:20\tTurban\t-0m33s\n 19:17:23\tVent Ovfl\t-0m29s\n 19:17:47\tBoop\t-0m05s\n 19:17:53\tB1\t--- d=08m06s\n 19:20:04\tVent\t2m11s\n 19:25:59\tP1\t8m06s d=18s\n 19:26:18\tB2\t8m25s d=02m45s\n 19:29:04\tP2\t11m10s\n 19:30:04\tV&amp;T Quit\t12m11s\n\n\t\t\t\t     \u03a3B=10m52s\t\u03a3D=11m10s\n\t* * * * *\n 15:02:04\t\t\t\n 15:35:03\tInt: 32m59s\td=03m42s D0\t\n 15:51:56\tInt: 16m53s\td=03m09s D1\t\n 16:09:40\tInt: 17m44s\td=02m56s D2\t\n 16:26:33\tInt: 16m53s\td=02m45s D3\t\n 16:46:07\tInt: 19m34s\td=02m57s D4\t\n 17:05:42\tInt: 19m35s\td=03m01s D5\t\n 17:22:23\tInt: 16m41s\td=02m57s D6\t\n 17:55:01\tInt: 32m38s\td=03m30s D7\/D0\t\n 18:11:19\tInt: 16m18s\td=03m04s D7\/D1\t\n 18:29:24\tInt: 18m05s\td=03m30s D7\/D2\t\n 18:45:39\tInt: 16m15s\td=02m56s D7\/D3\n 18:55:35ns\tWest Triplet d=02m13s\n 19:04:10\tInt: 18m31s\td=03m07s D7\/D4\n\t\t     Turban: 13m09s<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>Didn't get much sleep during the night, as I was busy documenting and editing and uploading videos.
