Went out to Grand expecting the next eruption to be in the dark. Did not expect it to be well after midnight.
At around the time I would have expected the eruption we got a strong, heavy overflow from Grand and the Turban eruption interval was 24-1/2 minutes. While not a Delay as defined, Grand and Turban acted as if it was for the rest of the wait. The durations on Turban eruptions got shorter as did the intervals. The final Turban eruption interval preceeding the explosive start of the One Burst Grand eruption was less than 14 minutes, and it took Turban over a minute to finally begin its eruption. The lighting by the moon, and the obscuring steam wasn't too bad, but not bright enough for us to seen any moonbows.

Came back out after dawn, and this time there was no wait for the One Burst Grand eruption. What little air movement was toward the south, although there was a steady rain mist coming down to the northern boardwalk were there was the view.

Checked out Economic before both eruptions. For the first, Economic was low, with the water level inside the inner rim and many of the runoff channels (especially the one under the boardwalk) showed no sign of being wet recently. For the second visit, Economic was in steady overflow and the under boardwalk runoff was wet.
Went down basin to take a look at the progress (or lack thereof) in rebuilding the boardwalk south of Giant. There old walkway has only been partly removed, and from a distance I could not seen any new sections. On the way back, I did manage to get a Rocket major eruption.
Like the morning eruption, we didn't have a long wait for the One Burst Grand eruption. An otherwise undistinguished eruption at midday with weather that was nicely sunny but a bit breezy at times.
After the Grand eruption, West Triplet started to erupt. As a Rift eruption is expected by midday tomorrow, I waited around for the end. It only lasted eight minutes, so no Rift eruption for at least a few more hours. Just before I left, Grand started having some small afterplay.

Was not surprised to see Rift in eruption when I came out for the next Grand eruption. Ended up waiting through a two hour series of Turban eruptions where the durations were short (around 3-1/2 minutes) while the intervals got shorter. Once they got around 16 minutes, I noticed that Rift was dying down. Half hour later, it quit as Grand started to erupt. We got a well lit two burst eruption where the durations were reasonable and ordinary.

Just before Grand, Beehive erupted. I watched it from the Sawmill Group.
It seems like every day over the radio I hear at least one report of a "thermal trespass" in the Biscuit Basin closure. I have yet to hear of anyone being cited for entering that closure. All that happens is that some or all of the group gets an identity check and a verbal warning. So if you are willing to risk the possibility of having a lifetime record in the national Dept. Of Interior "DOI-10 Incident Management, Analysis and Reporting System (IMARS)", you can get out there and look around and shoot your videos and selfies.
Plan ahead. Go out in the morning when the fog will help hide you. Go in from the Mystic Falls trailhead. Carry a radio that's tuned to the West Direct and West Repeater channels so you know when you've been spotted. Wear a bit of a disguise, in case you are seen. Something you would normally never wear, like a bright red MAGA ballcap, or a fluorescent orange jacket. Something that could easily be used as identification from a distance, and easily hidden when needed.
If you do get cited, have a lawyer ready so you can file a discrimination lawsuit. Just because you aren't a foreign tourist (frequent culprits) and despite your have spent years visiting this park, that doesn't mean you should not receive a verbal warning like everyone else. Enjoy!
I've been informed that 'coy' is an acronym from wildlife management jargon meaning "cub of year", a term that has escaped into the wild. I guess it's not surprising that a group that seems to enjoy using terms like "stall", or "crash", or "ernesto", or "delay" would readily adopt it.
