Frequent eruptions, but shortly after each of the (3) Three Crater eruptions, there was a longer interval, as if Little Brother skipped an eruption. Longer intervals didn't occur at other times. |

Have been watching as noted with eruptions every 2-3 minutes but LB has been draining bit by bit till pool between eruptions is barely visible from road. Eruptions are forceful and 10-15 feet high, though brief. |

I believe all the intervals recorded over this time span were closed intervals. |

All closed intervals (there's a hidden 1m interval in the GT postings). Erratic intervals, ranging from 1 minute to 18 minutes. All durations 2 to 3 seconds. |

Two very low, brief surges / boils. Not enough to call it an eruption. |

I watched 4 consecutive eruptions. Each was followed by 1 or 2 bursts from Three Crater a few seconds after Little Brother stopped. Some of these were quite large and vertical, as big as Little Brother itself.
Little Brother remained active later today and the next 3 days but I never again saw Three Crater acting in concert with it. |

Last entry on GT is Aug 15. Area around its crater is dry. Likely dormant now? |

Noticed a tiny sput in the catch basin /berm {ie pool of standing water within the berm} of LB. Eruption is all of 2 inches and is difficult to see without binoculars but seems to be a tiny perpetual spouter. Didn't know if it had been noticed before. |

Little Brother is erupting 5-10 feet high every 30-70 seconds (with outliers on both sides) . Preliminary observations and timing this morning suggests that it likes to slow down after an eruption of 3 crater. Detailed eruption entries and further observations to follow. |

Little Brother appears to be erupting about once a minute. GT tends to assume the second eruption is a secondary report of the eruption a minute earlier. |

Little Brother appears to be erupting once to twice a minute to 6-10 feet. So far all I have seen are single bursts. |
