----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Thu Feb 17 17:41:08 GMT 2000 Year: 00 Doy: 048 Observer: koon WEATHER COMMENT: Thu Feb 17 17:41:17 GMT 2000 Scattered cirrus, wind=10 mph from the SSE, temp=42 F. There was a light snowfall from those clouds that were up here yesterday. :14 GMT 2000 CHIP CHIP Start 7 Passband Patrol **MKIV PROBLEM**: Thu Feb 17 17:56:33 GMT 2000 I think that the apparent noise in the SW quadrant is due to uneven occulting. So I tried changing the O1 position and the occulting is worse in that area. I normally change this throughout the year and there is no problem, but the mechanism is at the end of the travel so I will have to change the relative guider position to get in-range with the O1 mechanisms. The spar guiding will be strange for 30 minutes or so while I try to get things adjusted correctly.

I may have to do more fine tuning later since the middle of the day is the best time to set these things. MKIV COMMENT: Thu Feb 17 19:39:54 GMT 2000 I finetuned the occulting centering, didn't need to change guiding for this. **CHIP PROBLEM**: Thu Feb 17 20:11:13 GMT 2000 Stalled with Program: 1082.847 Did a Kill/Run to fix it. Thu Feb 17 20:14:08 GMT 2000 CHIP CHIP Start 7 Passband Patrol **CHIP PROBLEM**: Thu Feb 17 21:44:33 GMT 2000 More tape problems, lots of errors on console screen: tape write -1 tape: I/O error Maybe this isn't a tape cassette error, if it is it usually says "media error" The Status window shows Program:1082.847 again, like the last stall, and the program is stalled again. I'll clean the drive before shutting down. **CHIP PROBLEM**: Thu Feb 17 22:08:16 GMT 2000 The tape C01044 was in bad shape when I removed it, tape was sticking out beyond the shutter and was crinkled, reminds me of the fate of several of my old 8 track tapes. I'll send it anyway since it is salvageable. I rewound the crinkled slack tape back into the cassette but I'll leave it there so the data scientists can look at the tape and figure out if they want to risk getting it stuck again in their drives or just salvage some of the data before the crinkles. If you lay the tape face down and look at the back of the cassette you will see a small lever on the right side of the tape that releases the shutter when you push it, then you can look at the tape condition at this bad spot. If you want to rewind the tape in a drive then you should manually rewind beyond the bad part by hand. To do this you stick a small screwdriver into the rectangular hole (near the bottom of the back side of the tape if the shutter side is up and the shutter release lever is to the right), in the hole is a button that you press downward while turning the takeup reel (right reel) clockwise with a large screwdriver in its center hole. When beyond the bad part you can rewind the rest of the way with a drive. I put a message with the tape to remind people to check this log and toss the tape when done with it.
