I will wait until we are done with the PSPT problem so I won't be interrupted and lose MKIII data. Pulled opal out after scan started.

Resuming Patrol. Mon May 11 19:41:32 GMT 1998 MKIII Start Patrol PSPT COMMENT: Mon May 11 19:45:37 GMT 1998 At first attempt, Haosheng could not move spar. I loosened the clutches and centered the spar-pointed it up, basically, and then retightend clutches. After running a bunch of diagnostics from Sunspot, Haosheng got around a situation where the sun got close, but the dec quit running to close in on centering. He said he moved the guider servos a bit closer to the sun and the dec began working again. He logged out and I did a 'Restart' from here. We'll see how it goes today. Haosheng is unsure if we are by the problem so if it works today, we will still need to run it tomorrow before we consider this problem gone.

Halted execution. PSPT COMMENT: Mon May 11 20:38:21 GMT 1998 Haosheng called and said he thinks he forgot to initialize the position once the guider locked on to the sun the first time today. That is probably why it lost the sun at the start of the next obs attempt. Restarted Run.
