----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Tue Jul 27 16:21:12 GMT 1999 Year: 99 Doy: 208 Observer: yasukawa WEATHER COMMENT: Tue Jul 27 16:21:34 GMT 1999 Cool, clear, brisk east wind, cloud bank very high to east. Tue Jul 27 16:28:24 GMT 1999 CHIP Startup--Initializing new tape Tue Jul 27 16:30:23 GMT 1999 CHIP CHIP Start Patrol Tue Jul 27 16:30:42 GMT 1999 PICS Start Patrol Tue Jul 27 16:32:03 GMT 1999 MKIV Start Patrol Tue Jul 27 17:00:50 GMT 1999 CHIP Bias **MKIV PROBLEM**: Tue Jul 27 17:01:19 GMT 1999 There was a funny in the NW sector of MKIV and MKIII images. Looked down tube and saw a large chip of something resting on the slot mask. Stopping to remove object. This is what might have caused the "chip" incident a few weeks ago. Tue Jul 27 17:13:41 GMT 1999 MKIV Start Patrol **MKIV PROBLEM**: Tue Jul 27 17:13:51 GMT 1999 "chip" was a piece of rubber gasket material, possibly from the air circulation system (corrugated aluminum hoses/filtration box/fans). I could not see anything inside the light tube that indicated any rubber gaskets, much less a broken one. Piece was approximately 2-inches long and 1/2-inch wide at its widest, kinda fingernail-shaped. It is out of the system now. **** EVENT COMMENT ****: Tue Jul 27 17:20:01 GMT 1999 Active region continues. PA 65-90. **MKIV PROBLEM**: Tue Jul 27 17:43:03 GMT 1999 Stopping MKIV to reboot the KCC to pick up new code that David hopes will reduce the noise in the MKIV. Tue Jul 27 17:52:36 GMT 1999 MKIV Start Patrol **MKIV PROBLEM**: Tue Jul 27 17:53:20 GMT 1999 Having difficulty getting barrel to go anywhere it recognizes. **MKIV PROBLEM**: Tue Jul 27 17:56:45 GMT 1999 Patrol is finally scanning, but I do not see any coronal signal in the image display.

Rebooted KCC to pick up new code. This time, I did an End Day (twice) to run the barrel to the north like when we shut down to allow the barrel to start at a familiar PA after the KCC reset. **MKIV PROBLEM**: Tue Jul 27 18:14:42 GMT 1999 Still cannot see image on display, even at the highest available gain (4). Assuming data is still there so I will run it, utilizing MKIII Xanim display to monitor corona until David gets back to fix the problem.

I will reconfigure dome shutter while the KCC is rebooting.

I will try powering down and restarting after I get back to idle.

May be down until David gets back from vacation Aug 16.

Stopped and rebooting.

Cannot keep both PICS and MKIV in slot at this time. **MKIV PROBLEM**: Tue Jul 27 22:34:13 GMT 1999 Determined that gains were set too high and image was saturated by looking at MKIV image at .25. Corona was visible and "hot" at this gain setting. David reset the gains and we now have a good range, corona is back! MKIII image gain was also changed so David adjusted it. Waiting for scan to finish to reset KCC to pick up new changes. Tue Jul 27 22:42:49 GMT 1999 MKIV Start Patrol **MKIV PROBLEM**: Tue Jul 27 22:47:30 GMT 1999 Both MKIII and MKIV gain ranges for the KCC display look good. Shutting down for the day before I break something else and David won't be able to leave for his vacation.
