2234 01 Sep 2015 @ 1423 --- Micah Kipple Front Vent splashing, drained.
2157 14 Aug 2015 @ 1628 14 Aug 2015 @ 1843 JSJ Oval Spring ~one-third filled at 1628. Basin nearly full at 1800. Full pool pulsing event at 1815. Pool calm at 1817. A second full pool pulsing event at 1828. Calm at 1829. Water level down a bit as of 1838. Even lower at 1843.
1610 18 May 2015 @ 1739 18 May 2015 @ 1930 JSJ During a Tardy cycle: whole crater observed to be water-filled at 1739. Full-pool pulsing at 1743-1744 and 1753-1754 and 1803-1804 and 1813-1814 and 1823 (2 more pulsing events were witnessed by others before these). The latter pulsing events resulted in slight overflow from 3 sites along the edge of Oval Spring's geyserite sediment border rim (1: NW side; 2: ESE side; 3: SW side). Observed Oval's water level was way down at 1930, after the end of Penta Geyser's 1827 to 1923 eruption.
