----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Wed Aug 25 16:28:59 GMT 1999 Year: 99 Doy: 237 Observer: koon WEATHER COMMENT: Wed Aug 25 16:29:00 GMT 1999 Clear sky, wind=10 mph from the SE, temp=46 F. Wed Aug 25 16:30:12 GMT 1999 CHIP Startup--Initializing new tape Wed Aug 25 16:34:09 GMT 1999 CHIP CHIP Start Patrol Wed Aug 25 16:34:09 GMT 1999 CHIP CHIP Start Patrol **MKIV PROBLEM**: Wed Aug 25 16:40:32 GMT 1999 Selecting Patrol didn't do anything, selector field went white but barrel didn't start scanning. Cycled main MKIV power, then barrel got stuck near a limit, turned off spar power strip and pointed barrel to other limit and turned power strip back on, went off to work on other problems, came back and the barrel was stuck on the limit again. Turned off MKIV main power, turned off the spar power strip, repointed the barrel, turned on power strip, turned on main power. MKIV COMMENT: Wed Aug 25 16:50:15 GMT 1999 lost tracking a few times while working on latest MKIV problems. **LOW-L PROBLEM**: Wed Aug 25 16:50:52 GMT 1999 L00621 was popped out of drive #1, data are going to L00622 in drive #0. Top amber LED on drive #1 blinking at 1 HZ. Installed L00623 in drive #1. **MKIV PROBLEM**: Wed Aug 25 16:56:34 GMT 1999 I clicked on the Begin Day field and then the Patrol field as I usually do, but still the scans aren't starting. Will have to go through the logs for the past few days and my email to see if I can find out what changes might be causing this.

I turned off the main MKIV power and Spar power strip, pointed the barrel to appropriate limit, then turned it all back on. But it looks like it is showing the same Access Fault lines in the Akamai window: Access Fault Program Counter: 0xe0c02f3c Status Register: 0x3004 Access Address : 0xe0c02f38 Special Status : 0x05e6 Task: 0x34946c "" value = 0 = 0x0 Wed Aug 25 18:00:08 GMT 1999 PICS Flat Wed Aug 25 18:00:58 GMT 1999 CHIP Bias Wed Aug 25 18:01:49 GMT 1999 CHIP End Bias Wed Aug 25 18:01:57 GMT 1999 CHIP Water Wed Aug 25 18:02:32 GMT 1999 CHIP End Water Wed Aug 25 18:02:41 GMT 1999 PICS End Flat Wed Aug 25 18:10:56 GMT 1999 MKIV Start Patrol Wed Aug 25 18:26:39 GMT 1999 MKIV Start Cal **MKIV PROBLEM**: Wed Aug 25 18:27:44 GMT 1999 Still can't get the desired files transferred during the calibration, without crashing the KCC. David changed the code back to previous code. I am taking a calibration, then will continue with regular Patrol.

There isn't a lot of movement available due to the mounts and/or cam mechanisms reaching their limits, and there is mechanical cross-talk between axes - especially near the limits. I tried taking out the setscrews in case they were limiting needed travel, but was able to find the best signal (at limits) without the setscrews causing those limits (I could get them back in after the limits were reached). So I peaked the signal while David verified values with me via telephone and the computer network, he was able to quantify signals by remotely using the akamai computer. It may be possible to increase the signal if that lens could be moved beyond the limits or if other optical components are realigned too. MKIV COMMENT: Wed Aug 25 22:35:35 GMT 1999 The scans look much less noisy to me.
