----------------------------------------------------------------
Highlights:
16:00 - 18:20 -> Production running.
18:20 - 19:14 -> MCC takes away the beam to do a test plan.
19:14 - 23:00 -> Production running with IHWP out
23:00 -> IHWP changed to IN
23:00 - 24:00 -> Production running
The Run Plan:
1. Production Running (with both arms!)
2. Rob Feuerbach might show up to do an alignment/Q^2 check. Then again, he might not! If he does not show up during the swing shift, he will come in during the owl shift, I am told by Bob.

The Run Down
16:00 - Shift starts off in production mode with both arms, and with the Compton running as well.
16:36 - PD calls from MCC and wants to get an idea of the swing shift program for tonight. So, I tell him that we are in production running, with the possibility of an alignment check late in the shift.
17:42 - MCC calls. They want to do a PZT scan, which will take a couple of minutes. I told him that he can do the scan when we reach the end of this run in about 45 minutes.
18:20 - Called MCC and told them we have reached the end of this run, so if they want to do their scan, they should do it now. They seem to be confused and ask if they can call me back in a minute. Now I am told that the scan will take 30 minutes.
18:30 - They call back and are starting the test they had scheduled. It should take "less than 30 minutes". They take the beam from both halls (A and B). (Yelena scoped out Hall B for us.)
19:07 - MCC calls and says that they are going to send us our beam again!
19:14 - We have beam, but it is pretty unstable so far. I had to reboot CODA for the Compton, but that is running again as well. The beam stabilizes after about 15 minutes.
20:02 - Compton CODA mysteriously died and disappeared without a trace. We are rebooting and restarted.
20:04 - Compton mystery solved! It was Hachemi!! He wrecked my Compton run from the back room!! The Compton DAQ is now restarted and running. Hmph.
23:00 - We reached the goal of 600k; IHWP changed to IN; flipper has been run, and we are taking data again.
23:41 - MCC calls. They want to redo their PZT scan at some point, so if we have an access in our future, they would like to do it sometime around then. I wasn't enthusiastic, so we aren't doing it now. [Note: Bob was even less enthusiastic about it when I told him later.]
Midnight - End of my shift! It was quite productive; Bob says we collected 1.2 C. Yay!! :) :)
