Quick update for the weekend. We'll have a quick meeting at 11:00 too.
We're progressing on the Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ central setting. We're currently on around 4.3k out of our 10k goal. At ~650-700 pions an hour, we're on track to finish this setting some point during swing. 

When we get it done, we'll go back to the LH2+ left setting and get ~2k more pions. This should take us ~4 hours. We then have a similar situation with the LD2+ left setting.

If we're done with all of this, we could either go for 10k on the left settings or just start taking some data on the Q2=1.60 W=3.08 x=0.15 left settings before the rotation.

As is, I'm happy to go ahead with the rotation tomorrow morning. We'll discuss this briefly in the meeting.
We have had a few other annoying and somewhat concerning (but not fatal issues) over the weekend too. There have been a range of white alarm/comms issues with different components over the weekend. Nathan has nicely compiled them all here - https://logbooks.jlab.org/entry/4031931

We have also lost the feed to the HGC pressure camera, this doesn't seem to be fixable remotely, so we'll have to fix it during the access for the rotation on Monday - https://logbooks.jlab.org/entry/4031976

As mentioned, a quick meeting this morning -
