----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Wed Dec 6 17:18:14 GMT 2000 Year: 00 Doy: 341 Observer: koon WEATHER COMMENT: Wed Dec 6 17:18:15 GMT 2000 Clear sky, wind=5 mph from the SW, temp=40 F. Wed Dec 6 17:19:05 GMT 2000 CHIP Startup--Initializing new tape COMMENT: Wed Dec 6 17:24:10 GMT 2000 Will start instruments after I figure out why the heater and light are up in the dome and turned on, not sure if I should move Spar, etcetera. Wed Dec 6 17:46:45 GMT 2000 CHIP Start 7 Passband Patrol COMMENT: Wed Dec 6 17:46:22 GMT 2000 The lamp and heater were used to try to heat up the CHIP plate temperature, they didn't work so I removed them. The plate temp is the same as it has been with the cooler out of order, about 13 C. The dome was about 45 F due to the heater, probably only about 5 degrees warmer than it would be without the heater, there is no insulation up there. MKIV COMMENT: Wed Dec 6 17:50:11 GMT 2000 The O1 guider is connected again and at both limits and making a lot of noise as it slowly self destructs, just like before I started leaving it disconnected. I'll watch it, if it doesn't get better by mid day I'll set it as usual and disconnect it, that way we'll still have a semi-functioning O1 guider to use for occulting corrections. The spill problems can sometimes be corrected in late morning by repointing the Spar and resetting the guider, instead of hooking up the O1 guider and changing the Spar guiding.

COMMENT: Wed Dec 6 18:47:29 GMT 2000 The Spar lost guiding so I repointed and reset the guider. There was spill around the East side of the occulter earlier, now after repointing there is no spill. **MKIV PROBLEM**: Wed Dec 6 18:52:01 GMT 2000 Now seeing possible spiil around occulter in North and South. The O1 guider is still connected at this time. Wed Dec 6 18:55:22 GMT 2000 PICS Start Patrol **MKIV PROBLEM**: Wed Dec 6 19:41:38 GMT 2000 Spill looks worse than ever. O1 guider is still connected. Will set occulting and disconnect the O1 guider. Wed Dec 6 20:00:40 GMT 2000 CHIP LSD **MKIV PROBLEM**: Wed Dec 6 19:50:57 GMT 2000 Occulting recentered and O1 guider disconnected. I still see some light pixels mainly grouped far out away from the limb in the NNE and SSW, they are evenly dispersed and so I think that is an indication of centering, also the solar image looks centered on the occulting disk when I look at it. If the occulting changes try repointing the Spar and resetting the guider, I think this will cure any image spill, without having to adjust the guider. This may be more of a Spar balance and flexure problem than an O1 guiding problem. With the O1 guider on, the occulting varied greatly as the O1 guider hunted to correct its own mechanical cross-talk, this is why I disconnected it a long time ago. The gears wear out from excess hunting and they are difficult to change. Gear dust is also created and that gets on optics. So the guider should be used sparingly.
