Observations for 2019 July 26


Another pretty dull day.

Another day where I spent a bit of time out at Grand to see if the newest changes in activity are changing further, or going to stabilize for a while. It appears that it's the latter. Sput D (Delta Geyser?) still seems to erupt at about twenty minute intervals, but otherwise is independent of Turban. Sometimes I was seeing it in the middle of the Turban interval, other times at the end of Turban's eruption.

After Grand West Triplet will flow heavily for about four minutes, without any activity in the sputs. That's the last time it overflows, even as Sput D continues to erupt after Vent and Turban continue.

Other good new of the day were the two Two Burst Grand eruptions. There was also a delayed eruption that was preceeded by about a minute of Grand booping, including one that had to be well over two meters high.

Also got to see two Oblong eruptions from Grand. Didn't notice the first one in the morning until it was underway, but in the afternoon I noticed that the steam was more than a wisp from down there, and over the next minute or so it built in volume until I finally got a small surge. That eruption had at least one burst well above the top of the dead tree.

Also down basin it looked like Grotto had a Marathon eruption. Bijou was quiet most of the day. Watching the Grand Group changes is cutting into opportunities to check on Grotto and Giant.
