Operators and commissioners were reminded to check the SDF file for changes. There were problems with locking last night due in part to the ITMY OpLev. This error was apparent when looking at the SDF overview. All were reminded to aLOG, aLOG, and aLOG. The aLOG is a valuable repository for documenting the many things that happen during a day. When in doubt aLOG it. The kitchen sink has been fixed. The Facilities folks asked that food scraps not be put into the sink, as they cause plugged pipes. Food scraps should be put into the compost bins or at the least put in the garbage, but not down the sink drain. Repairs to the RO system are complete. There is no potable water in the staging building due to a water leak. Beam tube cleaning continues. No safety meeting for today. Charge measurements will be taken today at both end stations.
