Woke up shortly before the alarm, and within a minute or two got the Beehive Indicator call. This time I only made it to the Firehole River bridge before I heard the roar of Beehive's eruption. Did get as far as Anemone (both vents were erupting). Also, Little Squirt was in eruption, and the alter ground near the boardwalk was steaming heavily.
Went back to the cabin to reconfigure, then headed out to Grand as it was almost 15 hours since the eruption we saw yesterday. Arrived to find Grand in overflow. Turns out that, based on the secret NPS time, I probably saw first overflow.
For the next couple of hours, it was a series of undistinguished Turban eruptions. Finally, West Triplet started to erupt, and eruption that lasted over an hour. During the middle of that eruption, I again saw slight steam coming from the location of East Triplet. Finally, after about fifteen minutes of heavy steaming, Rift began its eruption.
That eruption only lasted about 46 minutes. Two Turban eruption intervals later, Grand had its first good overflow, and we got a steamy but backlit One Burst Eruption.

When to return to Grand was an open quesiton. I didn't want to go too early, as these long waits in the cold and wind are tiresome, but didn't want to miss a short interval. Settled on getting out at around the 6-1/2 hour mark. So Grand erupts at just over six hours. I'd just finished something to eat and was getting properly configured.
Instead I went out to wait for Uncertain. Sawmill had a short, no overflow eruption while I was watching and waiting for West Triplet to quit, and see if Rift would start. It didn't. Then Sawmill starts another eruption about 45 minutes later, this time getting strong and overflowing.
By this time Uncertain had been splashing and gurgling nicely, so three minutes later, it also erupted.
At that point it was getting colder and windier, and it looked like the precipitation could start soon.
