The next hot period was just under 6 hours after the previous. It had a restart, but that pause was long, the restart was short, and there wasn't much going on besides Feather. It was perhaps the weakest of this series over the past few days.
Since Grand and Giant were not in sync, waited less than a Turban interval for a One Burst Grand eruption, then headed back to the cage.
Almost immediately, there was a long Bijou Pause. Even though 4m22s long, Mastiff never had water. This seemed a good sign, that there might finally be a longer interval. Which is what happened. Three hours later, we finally got the hotperiod, with an interval of 8-1/2 hours. The surging in Giant was great, but not enough to result in an eruption.
After that, had another opportunity for a One Burst Grand eruption. Which is what it did.
At sunset we had yet another hot period with an interval of 5-1/2 hours. It wasn't as weak as the early morning, but was pretty obvious that it wasn't going to result in an eruption. It took a long time (2m34s) for Feather to restart, and when it did, it was the only vent erupting and it lasted only 3 minutes.
Based on this, I figured that I next needed to be out in the cage after midnight. So it was quite a surprise to be awakened well before the time my alarm was set by Tara reporting a hot period in progress. One with an interval of a little over 4 hours. Started the mad dash to get dressed and ready enough to head out. Didn't get very far when she announced that things were winding down. Was a relief, but now I wasn't sure when to head back out. Decided that I should be there in time for another four hour interval.
