Difficult morning for locking. 

   After many lock failures, and at Jenne's suggestion started to run another an Initial Alignment. One had been done earlier during the day. No problem with ALS green. Could not get Input_Align to complete. It would grab lock with good power for a second or two and then drop. Ran through a couple of things with Sheila on the phone, but made no real progress. Sheila is coming in to work on resolving this problem.
