Instead, it erupted just after midnight, so I went out into the dark, cold, and damp about six hours later. It got lighter, but breezy and gray and still cold.<\/p>\n\n\n\n<p>Arrived in time to catch the start of West Triplet, and then the full interval leading up to a Turban Delay Interval. Fortunately, West Triplet ended without Rift starting, and the delay was only for three Turban eruption intervals.<\/p>\n\n\n\n<p>The One Burst Grand was interesting only because it lasted for nearly eleven minutes, and Vent &amp; Turban did not quit. At first I thought they had, then there was a resurgence from both geysers. Vent went into a loud roaring phase. I stuck around a little bit on the very off chance this could lead to an afterburst, but over the next few minutes Grand never showed any splashing.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">2026-Sep-23 : 08:10:37 D3\/T1C\n\n 08:10:25\tTurban\t-0m12s\n 08:10:37\tB1\t--- d=10m58s\n 08:13:32\tVent\t2m54s\n 08:21:36\tP1\t10m58s\nVent &amp; Turban continue\n\n\t\t\t\t     \t\u03a3D=10m58s\n\t* * * * *\n 06:42:25\t\t\td=04m18s\t\n 06:57:41\tWest Triplet d=32m41s\n 07:12:52\tInt: 30m27s\td=04m58s D0\n 07:30:23\tInt: 17m31s\td=03m28s D1\n 07:48:07\tInt: 17m43s\td=03m47s D2\n\t\t     Turban: 22m17s<\/pre>\n\n\n\n<p>In the afternoon, Grand waited for West Triplet to erupt.
