Comments:Observed "Pressure Cooker Mode" begin at 20:50 from steerage after a very strong single minor around 20:42 that sent significant runoff down SV channel. Very quiet from 21:15 until a long series of increasingly powerful minors began around 00:30. Minors began to pick up vertical action, follow up and water volume at 01:00. NV continuous water for at least 63min, SV tried to switch to steam as early as 01:42 but could not fully switch. NV and SV spent the last 20-25 minutes of water phase trading back and forth as primary water spouter. Both vents in steam at 02:19. .
