maybe not an eruption, but the bowl is fuller than usual and water is splashing from 3 to 12 in high continuously. As I watched for three more minutes the bowl continued to fill and the splashes became taller. Perhaps it will become an eruption after I leave. |

Although low, there seems to be a pulsatile or percussive quality to some of the steam that makes us wonder if something is happening. Steam "cloud" doesn't look quite wide enough to fill width of Churn's basin, though. |

(wc) late 0833 to early 0835. Looked very promising with dense steam rising behind boardwalk, perhaps on a hair-trigger. Steam began decreasing after ±20s (early 0834), with early 0835 back at ~regular steam output. |
