Quiet - left channel with good flow - right channel is wet but not steadily overflowing - upon arrival it looked like it just regained ovfl after a minor but stayed the same for 2.5 hours - as Constant heated up prior to erupting poor Whirligig looked cold in comparison |

Perhaps a very weak minor. There was stronger overflow, some churning, and the rooster tail vent bubbled. Nothing went airborne |

As I approached Porcelain basin I saw that Whirligig's pool was VERY LOW. ~5'. I just missed a full eruption. Walked down and the pool was filling but still had 4' of exposed red. Walked away figuring I had a long wait and was surprised when I got above Hurricane Vent to see Graceful and heard it ie @ 1839. Pool was NOT in overflow when it erupted! End 1841. |

NOTE to future researchers - Missing from the data here is a Whirligig minor at 0541 and a full eruption at 0633. Based on the YVO temperature trace, the interval information here is incomplete. These eruptions were disputed and deleted, but I believe they should be included, or at least a future researcher can make the choice to include them, or not, in their study of Whirligig, so I note them here. |

From this time the number of non-minors increased while there were hardly any minors. Also no minors between the last two non-minors. In previous years, an increase in non-minors while simultaneously the number of minors decreased, announced the arrival of a disturbance. |

Minors started to become more spaced out around 1500 January 17 and occurred roughly hourly by 1800. This culminated into the first non-minor since ±April/May 2020 at 0220 January 18. It has since had two non-minors before logger data was uploaded @ 1200. Previous disturbances featured Whirligig switching from exclusively minors to exclusively non-minors for roughly the duration of the disturbance. Therefore, my assumption is that there's a disturbance currently ongoing at Norris. |

Whirligig tried to start. The pool had a big convection and the rooster tail vent erupted for15-20 seconds, then went quiet and the pool dropped about a centimeter or less. No eruption from the main vent. |

It looks as if Whirligig has switched, without much of a transition, to an eruptive pattern consisting out of largely 'major'/'normal' eruptions since 0000 on 30 March 2019. |

Whirligig seems to have entered a phase with what seems to be very frequent minor eruptions (up to 6+ per 3 hours) and few majors (one or two or even none per day). This seems to have developed gradually since December 2. |
