In overflow at 0710. Based on strength of overflow, I believe it is a continuation of the overflow that started at 0615.
0857 very strong boil that I thought was the start of an eruption, but didn’t trigger an eruption. Eruption finally started at 0943. Overflow greater than 153 minutes. |

Overflow with low boiling until 1549 when pool boiled up 2-3 feet high. After 2-3 minutes of vigorous boiling, the pool level started bouncing in and out of overflow with boiling that looked like post-eruptive inside the crater rim boiling when the pool was below overflow. At 1609 the pool dropped several inches, ending the in-and-out of overflow activity. |

First time I was able to see water in the crater was at 1056. Water level dropped. On the first rise, which started at 1116, the pool almost reached overflow. Water level started dropping at 1132. The water dropped several inches but did not crash out of sight. The water level started rising at 1148. |

Wild Phase Continues. Sets of bursts:
1845-1853 Decent strength.
1859-1906 Looked like an OK second, fifty feet with a blue bubbles
1913-1918 OK second, fifty feet and a blue bubbles
1926-1932 Meh, thirty feet
1940-1946 Decent, 60ft with good bubbles pops and small waves
1954-2000 Strong, maybe 75ft, counted six blue bubbles this series
2008-2014 Super strong blue bubbles start very wide, lackluster rest
2022-2028 Medium strength
2035-2041 Strong with great bubbles to fifty feet
2048-2054 Good with many strong bubbles
2101-2107 Great with many nice bubbles, one very wide burst
2115-2121 Good again, wide burst but not really a bubble
2128-2134 Amazing, strong bubbles and a decent wave
2142-2148 One spectacular bubble to fifty feet
2155-2200 Very strong, nice bubble to sixty feet or so. Quite a few forty foot bubble bursts
Overall was bursting for around 6 minutes and then quite for 8. Bursts put a decent amount of water outside the crater. the strongest parts of the series tends to be the first three minutes. |
