Today Grand decided that it needed to put in some longer intervals. Had no intention of going out in the middle of the night, so relieved to discover that would have had to wait a couple of extra hours, until dawn. In the middle of the day the interval was almost as long, which allowed a huge accumulation of people.
Again, another day of waiting for Giant. At least there was a hot period during the night, and then another one near sunset. I didn't see that one, but nice to know that they can happen more than once a day. In this case, appeared to be about 16 to 18 hours between them, which seems to fit the pattern established during the buildup to the last eruption.
