Temp=45F. Thu Oct 13 16:46:49 GMT 1994: Patrol Start MKIII COMMENT: Thu Oct 13 16:51:31 GMT 1994 MKIII looking at the wall. Standing by to start when it clears dome. Thu Oct 13 17:02:03 GMT 1994: Calibration MKIII COMMENT: Thu Oct 13 17:11:54 GMT 1994 MKIII has cleared the dome. MKIII COMMENT: Thu Oct 13 17:48:52 GMT 1994 Cathy has alerted us to flakiness on Chan 1. Checked monitors on chan 1 and found it basically dead this morning. There has been a lot of fiddling with the channel as part of it, from the DCSB on down has been used in the chan 2 work. Will check the system out. MKIII COMMENT: Thu Oct 13 17:53:41 GMT 1994 Need to stop scan to check out chan 1 further. Thu Oct 13 18:01:59 GMT 1994: Calibration MKIII COMMENT: Thu Oct 13 18:07:03 GMT 1994 Chan 1 data pulses were missing. Checked connection at the trapeziod box on the rear of the MKIII. Reconnected lemo connector and got the pulses back. May have been a poor connection, or (HORRORS) a bad connector. If channel 2 work is to continue, I will have to continue swapping those fragile connectors.

DPMON COMMENT: Thu Oct 13 21:50:12 GMT 1994 ADR hadn't reset in the sunlight before turning it on so it did not move dome. Reset the timer relay.
