The wait for the morning Grand wasn't too horrible. The rain had already started as I arrived in time for the Turban eruption prior to the Delay Eruption interval. The rain never got too strong during the next hour.
The rain had mostly ended when the One Burst Grand eruption started explosively, with a wide jet to at least ten meters. It was clear enough that I could see the details of the rest of the start of the eruption. I was able to get back to the cabin without encountering anything more than a slight shower.

With the rain continuing, it was a good time to be indoors. Finally, it was time to head back out to Grand. About twenty minutes after arrival, West Triplet started to erupt. It ended and Grand had shown no sign of any attempt at erupting, so it was wait for West Triplet to recover.
About an hour later Grand filled slowly and nicely, and we had a long One Burst Grand Eruption. Unfortunately, the overcast kept the eruption from having rainbows.

Afterward, I headed to the Bijou Cage for an hour, just to see how things are progressing. If I did not know of the eruption, and had last visited on Saturday, I'd think that not much had changed. During the hour Bijou never stopped, and was on strong. Mastiff was having strong depth charging from the front vent, and I saw two good Mastiff back vent surges. The second one lasted about 20 seconds, and was almost three meters high at one point. The Southwest Vents were making noise, too.
