Observations for 02 November 2013
Since I went out for one nighttime Grand, might as well go out for another. It was still partly overcast, with an occasional breeze, and much like a typical summer nighttime wait. This time ended up waiting a few Turban intervals for another one burst eruption, but this time it was initiated by Grand.
The day started out overcast and breezy, and slowly changed to sunny and breezy.
Of course, the next interval had to make up for the previous short intervals. First, at the six hour mark there was a Turban interval of around 35 minutes. During that time, West Triplet started, and a half hour later Rift joined in. That West Triplet eruption lasted for an hour, as did Rift, Then Grand took its time. After several long intervals and unimpressive fills and Turban eruptions, we finally got a short Turban interval of about 3m30s. With that, I expected Grand in another couple of Turban intervals.
As it turned out, it was four Turban intervals, and each Turban eruption was just as short. This is something I've not seen much. Each fill of Grand's pool started early, around 11 minutes, and by 14 it would look really good. Then drop. Finally the pool held, and through the steamy breeze we could see the waves on the pool.
The eruption, at least, compensated for the wait. We not only got two bursts, but the wind died down as the second burst started, so we did get to see the full height. This was unlike the Beehive eruption that took place about an hour earlier, where the wind picked up and carried the truncated water column north toward Lion.
I also wasted some time down at Fan & Mortar after Grand.
The long Grand interval wasn't totally disappointing, as it did have the side effect of pushing the Fountain and Grand windows apart. So I went out to Fountain on the off chance that Morning could erupt. As it turned out, we got Fountain, and a short eruption lasting 34 minutes. While there, the weather started to deteriorate. The Fountain Group always seems windy, but this was more than usual. But the sky was still pretty clear, and the sunset was a bit colorful.
An hour or so later, when it was finally time for Grand, the weather had gotten worse. It was still windy, and there were occasional chunks of frozen precipitation. But at the same time, the half the sky could be clear, with even the Milky Way visible. It was also warm enough that the boardwalk downwind of Sawmill was not icy on the walk back. The night was the opposite of the previous night in just about every way.
The Grand eruption itself was a disappointment,too. The first burst only lasted 7m20. That short meant we should get a second burst, and we did. And that's all we got, even though the total eruption duration was 9m35s. Can't tell at night, but it sure seemed that Grand didn't even try for a third. In years past, having a first burst that should would bring out the hope of four or more bursts. Now it just means that you should get a second.
