The previous night had high cloudiness, enough that I decided I'd rather get some sleep. But this night was clear. Got out to Grand in time to catch a full Turban eruption interval before the main event, and as I noted yesterday, there was an eruption of Sput D a few mnutes before Grand started. There was also a loud eruption of Old Faithful, almost as loud as the eruption of Daisy a few minutes later. The boardwalk north of Grand was starting to ice up after the One Burst Eruption.
The sky was clear and the moon was obviously less than full. As we were untying our bikes, realized that it was time for an eruption of Castle. So waited a bit in the cold, with an elk bugling somewhere for at least 1/2 hour. There were a few splashes, and I was feeling the cold and had decided to head in when the eruption started. For the first eight minutes or so there were lots of short pauses as if it was trying to stop. Then the water play became continuous. When the steam phase started, a low moonbow was visible at the top of the cone if you stood directly between the geyser and the moon.
The morning warmed up nicely, considering how cold it had been a few hours earlier. As I walked toward Crested Pool, it had one of its huge boils, easily 3-4 meters high, lasting only a few seconds. I was wondering if I should get out my camera, but it ended before I could move.
I got to the Grand Group just I received a radio call that Beehive's Indicator was showing water. I decided to stay put, and was rewarded a few minutes later with an eruption of Oblong. Apparently it has been seen via the webcam just after midnight, so this was around an eight hour interval. It was still pretty steamy, but I could see bursts in there, but none of them were particularly big. The duration seemed normal, too.
Grand was again preceeded by Sput D, and it had a fairly long burst, about 9m45s. So it was a pleasant surprise to see water in the pool. Was to the north of the geyser, where the eruption had been backlit,and it was easy to see the sun's reflection on the swelling water. Was quiet strong burst with the small breeze pushing the steam toward the west. As I was leaving the area, the breeze turned into wind.
At the five hour mark, I wasn't thinking about going out to Grand because it had started raining, with lightning and dark skies. A half hour later, the rain had stopped and there was even some sunshine between the clouds. So I headed out, since waiting in the rain is much easier than heading out in it.
The rain never returned, and it was another One Burst Grand eruption, but still nice to see. Was a bit of a surprise, as the Turban interval was exactly 20 minutes, which is short for this year. But a couple of boops got my attention just before the start.
