Lockloss @ 11:07
PI mode 27. I damped mode 28 then, thinking that I defeated it, went to get a cup of water. When I returned, mode 27 was quickly rising and I got it to level out but couldn't damp it before it broke.
Back to Observing at 11:45
Another lockloss at 12:10 due to PI mode 27. I couldn't seem to get it to go down. I could get it to almost level out, but never bring it down. I did not try changing the gain, I will next time.
Observing again at 13:07. Range says 79Mpc!
