Rift erupted overnight, so not surprised to find that Grand had not yet erupted at dawn. Unfortunately, was preparing to head out when it did erupt. So went back to sleep for a few hours, then went out to Geyser Hill for the morning Beehive eruption.
Lion had been last seen almost 24 hours earlier, so decided I would wait over there. But it was cold and windy, and after about an hour or so, decided I'd had enough and headed in. Got as far as the Firehole River bridge when I heard the radio call for the Indicator. During most of the time the Indicator was erupting, the wind was moving the steam toward Plume, but as usual, it shifted to the north as the time for Beehive to start got closer. I decided to risk staying in place, and turns out I didn't have to worry. Being so close means that one doesn't notice the wind-sheared eruption as much.
After that, it was time to head out to Grand again, with the expectation of a longer wait due to Rift effects. But the interval was just over seven hours.
We've noticed recently that many Grand eruptions have Vent & Turban ending, with fewer where they continue. These Quit type eruptions are the result of either multiple bursts or long One Burst eruptions, while the Continue type eruptions are those that are a short One Burst Eruption. When we've had a shorter eruption, we end up getting a second burst that results in a Quit. That was the case again with this eruption, where the first burst lasted over 9-1/2 minutes and we still got our second burst.

Having expected to wait a while at Grand, decided to continue on down basin and see what Fan & Mortar had to offer. Went there also to test out some new features in my geyser logging application.
Arrived to find that everything was quiet. I thought I saw River and the other Fan vents start, but that activity only lasted a few minutes. Then Bottom Vent started splashing, and I saw splashes in Main Vent. The activity in Main Vent lasted for over thirty minutes, and some of the splashes were wide and as tall as the formations to the north/right. Bottom went into a full eruption that also lasted over half an hour.
The remainder of the cycle was anticlimactic, as the Fan Vents never came close to showing any good activity. The only good thing to note is that Angle Vent was quiet except during the period of time when it needed to be on after High and Gold were fully engaged in erupting.

Arrived out at Grand for the evening eruption just in time to see the first Turban eruption after a Turban Delay interval. From there we had to wait about two hours for the seventh in a series of similar Turban intervals and eruptions. When Grand finally erupted, Turban preceeded some booping by a few seconds, then the first burst lasted just over eight minutes. The total duration was just under ten minutes, which was short enough that Vent and Turban did not quit.
