Webcam was on Pump entire time and I watched consistently. This time span can be considered a sample of current activity. |

Pump was not covered by OF steam for long periods of time today. I wrote down a lot of times but it will take forever to copy them all. If anyone ever needs them let me know. It looks like it is still erupting every 5 minutes or so. |
