----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun May 23 16:52:39 GMT 1999 Year: 99 Doy: 143 Observer: koon WEATHER COMMENT: Sun May 23 16:52:42 GMT 1999 Thin cirrostratus, wind=10 mph from the SE, temp=47 F. Sun May 23 16:56:32 GMT 1999 MKIII Start Patrol Sun May 23 16:56:39 GMT 1999 PICS Start Patrol Sun May 23 17:00:24 GMT 1999 PICS Flat Sun May 23 17:01:29 GMT 1999 PICS End Flat **LOW-L PROBLEM**: Sun May 23 17:52:40 GMT 1999 Program was crashed due to an apparent power outage yesterday afternoon. I tried setting the autoexec back to the previous state where it would automatically restart the program after a power outage and that worked but I changed it back so that we have to manually restart the observing program after doing the following test. I cycled the power to the PC while the program was running and data were going to each of the 2 drives and found that we may lose quite a bit of data if we allow the autoexec to restart lowl because it always tries to write to drive#0, so if the tape on that drive already had data on it that data would be overwritten. It seems better to possibly lose part of a day of data by having to manually restart the observing program than risk losing a week of data by allowing the program to be automatically restarted. Later when we put the LOWL on the UPS then this won't be a problem at all. I removed L00600 from drive #1 and put L00601 in drive #1 so that I can continue my test to see if data will go to drive #0 without problems after the tape in drive #1 is full. I also installed L00602 in drive #0. **MLSO PROBLEM**: Sun May 23 18:06:39 GMT 1999 Power outage yesterday, I had to log back into the GONG terminal and reset the answering machine clock and restart LOWL.

Installed the hose clamps and coolant that I bought yesterday in Hilo. The first set of images look out of focus. GONG COMMENT: Sun May 23 20:34:57 GMT 1999 Going down to the shelter to check on a weather chassis problem. GONG COMMENT: Sun May 23 20:46:02 GMT 1999 Back from the shelter, all is well now I think. **PSPT PROBLEM**: Sun May 23 20:46:39 GMT 1999 Stalled with a message about the dome position on the PC, it looks like the program is still trying tomove the dome even though I asked Haosheng to remove the automation code and he said he did. We can't use auto dome pointing this time of year. I'll check it out when I get a chance.

I commented out a line in two files. **PSPT PROBLEM**: Sun May 23 21:36:40 GMT 1999 The Blue, Red, and Ca K images looked out of focus, but now the images being used for the calibration look sharp. I think every is OK again.

PSPT COMMENT: Sun May 23 22:33:28 GMT 1999 I replaced the Declination limit sector ring with the new revised (larger) ring. It gives about 16 degrees extra range beyond what we need for year round Dec guiding. I aligned it with about 10 degrees extra on the North limit side since we are only about one month away from the Northern extreme. This should work, but if it doesn't we'll know by the end of June.
