The IR sensor for CO2Y was intermittently going into fault. I resat the connector on the sat box and it seems to be okay now.

Today during maintenance the CO2Y laser tripped off 3 times. The first one we figured was due to cable pulling activity in the area, the second was a bit more of a mystery, and the third made us think there was definitely something wrong. Ryan C restarted the first two at the control box, needing to power cycle it at least once each time. The third time I went out there and noticed the IR fault light going on and off. I touched the cable that goes to the IR sensor itself and the lights on the IR satellite box went red. Simply placing my finger on the cable near the connector on the box was enough to bring it into fault. I checked the connector there and it had some play in it, so I tried to seat it a bit better and then it seemed to not be as sensitive to me touching it. I turned the key off and on again and it was good to go.

Because this last trip happened while we were powering up to 25W, there was about 20 minutes or so when CO2X was on at its nominal annular power, but CO2Y was off (~2107-2131UTC). Perhaps this is an interesting bit of time for someone to look at?

We ended up losing lock when powering up to 60W. Perhaps I should have waited longer after CO2Y was back to let it "catch up" to ITMX's thermal state.
