----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Wed Aug 27 16:30:11 GMT 2003 Year: 03 Doy: 239 Observer: yasukawa WEATHER COMMENT: Wed Aug 27 16:30:46 GMT 2003 Cool, clear, light south breeze. COMMENT: Wed Aug 27 16:31:02 GMT 2003 No observations yesterday due to illness. Wed Aug 27 16:36:11 GMT 2003 CHIP Start Patrol Wed Aug 27 16:36:21 GMT 2003 PICS Start Patrol A NEW TAPE HAS BEEN PUT INTO KAIEE DLT DRIVE, Wed Aug 27 16:41:00 GMT 2003 MKIV COMMENT: Wed Aug 27 16:58:48 GMT 2003 Centering O1. Mk4 has just cleared dome cylinder. Wed Aug 27 17:00:28 GMT 2003 MKIV Start Patrol PSPT COMMENT: Wed Aug 27 17:01:35 GMT 2003 Starting up. Foukal support filters have arrived. I will run a set of observations with the original PSPT red and blue filter in place to get a baseline impression of what the exposures should be before swapping-in the test filters. PSPT COMMENT: Wed Aug 27 17:16:22 GMT 2003 Observing. **PSPT PROBLEM**: Wed Aug 27 17:22:51 GMT 2003 ND filters on Foukal set were "popped in" and needed to be re-seated in mount. Probably due to expansion of bubble-wrap at high altitude applying pressure against the filters held in by tape on the edge. PSPT COMMENT: Wed Aug 27 17:29:29 GMT 2003 Stopped observation. Swapping filters. PSPT COMMENT: Wed Aug 27 17:40:53 GMT 2003 Foukal filter set installed. Observing. **PSPT PROBLEM**: Wed Aug 27 17:55:39 GMT 2003 "Blue" filter image is overexposed to saturated, "red" filter is very dark, no image visible. Stopped observations to attempt to find ND filters among the spares sent with the filters that will compensate for transmission.

Compensation will have to be via software. MKIV COMMENT: Wed Aug 27 18:12:05 GMT 2003 Centered O1. Wed Aug 27 18:13:13 GMT 2003 MKIV Start Cal **PSPT PROBLEM**: Wed Aug 27 18:15:12 GMT 2003 "Red" filter ND is very dark. I will swap the "red" filter's ND and the "blue filter's ND. Wed Aug 27 18:33:00 GMT 2003 MKIV End Cal Wed Aug 27 18:33:11 GMT 2003 MKIV Start Patrol **PSPT PROBLEM**: Wed Aug 27 18:34:05 GMT 2003 NDs swapped. Observing. **PSPT PROBLEM**: Wed Aug 27 18:42:55 GMT 2003 ND on "blue" may be too dark, centering routine thought PSPT was in clouds. **PSPT PROBLEM**: Wed Aug 27 18:43:54 GMT 2003 All images were dark. Found spar off pointed. Restarting observations, may need to manually point spar to test ND exposures. **PSPT PROBLEM**: Wed Aug 27 18:51:58 GMT 2003 Guider could not point due to low intensity of "blue" filter. "Blue" image dark. "Red" image was saturated--more than occurred in previous test with the ND on the "blue" filter. Stopped and I will swap the ND filters back to original filters. Looks like exposure will need to be set with software. COMMENT: Wed Aug 27 19:26:22 GMT 2003 Stopping to reconfigure dome shutter.

Filters re-installed, restarting observations. MKIV COMMENT: Wed Aug 27 19:32:55 GMT 2003 Centering O1. Wed Aug 27 19:33:26 GMT 2003 MKIV Start Patrol Wed Aug 27 19:33:19 GMT 2003 CHIP Start Patrol Wed Aug 27 19:33:31 GMT 2003 PICS Start Patrol **PSPT PROBLEM**: Wed Aug 27 19:45:37 GMT 2003 Stopping observations with Foukal set. **PSPT PROBLEM**: Wed Aug 27 19:47:25 GMT 2003 I will try to get a good exposure by stacking available filters. WEATHER COMMENT: Wed Aug 27 20:17:15 GMT 2003 In cirrus. **PSPT PROBLEM**: Wed Aug 27 20:38:28 GMT 2003 Cannot do a good job of stacking filters. Mount holes don't align with the filter stack extending down. I slipped the additional filter on top of the bandpass filter to get the ND holder to align. This situation means the added ND filter is not tilted and not in contact-much less greased to the mounted ND filter. **PSPT PROBLEM**: Wed Aug 27 20:49:17 GMT 2003 OK, I found a decent combination of ND filters for the Foukal "blue" exposure. Working on "red" stack now. **PSPT PROBLEM**: Wed Aug 27 21:15:18 GMT 2003 OK, again. I found a decent combination of ND filters for the Foukal "red" exposure after a couple of tries. This stack fit in the mount without compromising mounting hole alignment. Observing. **PSPT PROBLEM**: Wed Aug 27 21:22:10 GMT 2003 Exposures and focus look fairly decent. Once Randy takes a look at the images, only slight touch ups in software controlling exposure and focus may be needed. WEATHER COMMENT: Wed Aug 27 21:35:27 GMT 2003 Still in cirrus overcast, stopping MK4.
