[Geysers] Anemone concert observations 01-09-13

[Micah Kipple]

On 01-09-13 from 1649 to 1724 I was treated with the somewhat rare opportunity to Observe Anemone's behavior on the streaming webcam. At 1649 I noted that Big Anemone erupted, (when it erupts at this time of year there is a conspicuous steam cloud), upon announcing my observation, the camera operator zoomed in on the area, since visibility was limited and the window for various geysers elsewhere were nowhere close. I saw that Little Anemone was ie at 1650, which led to my conclusion that the Anemone complex had just undergone a concert sequence. 

9 minutes later, (A ten minute interval for Big) Big erupted again, this time Little was quiet, no concert. Based on my studies from labor day week, When Anemone is in a concert "series" it has concerts every 20 minutes give or take. so I guesstimated to that the next eruption would be a concert, and that it would occur around 1709. Again, drawing from my observations from last summer, I forecasted that Little would begin erupting around 1707. and it did. a minute later Big joined in for a Concert Sequence. After Big shut off, little continued for around a 3 minute duration, and then the system entered a "quiet period". 

The cam then panned away and down basin, so I continued (as best I could) to observe from the static cam. I caught another possible concert series at 1724, although I'm not sure because that would be two concerts back to back and I have not witnessed that before. 

A quick note of concern for me. For all three Big Anemone eruptions that I witnessed on the streaming cam, the duration seemed to be 20 seconds or less. this is very disconcerting to me because if that is the case, then the durations have halved in length since the summer. It will have to be something to keep an eye on as I watch for it more through the season.
