Comment--Sat Apr 20 17:44:38 GMT 1996 Work is being done on the CHIP, so the spar is getting bumped around a little.

CHIP Comment--Sat Apr 20 18:33:17 GMT 1996 Electrical noise is improved from yesterday, but still present at a low enough level that averaged images making up the hsr looks quite good. Polar plume at north pole right over an X-ray point. New AR in East. tiny prominence most likely at about 280deg CHIP--Sat Apr 20 18:34:50 GMT 1996 CHIP End Patrol CHIP--Sat Apr 20 18:58:42 GMT 1996 CHIP Start Patrol CHIP--Sat Apr 20 19:01:52 GMT 1996 CHIP Filemark CHIP--Sat Apr 20 19:03:04 GMT 1996 Flat CHIP--Sat Apr 20 19:08:27 GMT 1996 End Flat CHIP--Sat Apr 20 19:14:44 GMT 1996 CHIP End Patrol CHIP Comment--Sat Apr 20 19:22:17 GMT 1996 Did a flat at 1900 which looked good from this end. Meadured focus here with image offset 510 arc seconds as a compromise between disc center and limb. Best resolution at 21000 microns focus setting was 7.5 arc-seconds gaussian full width of derrivitive of limb profile. WEATHER COMMENT: Sat Apr 20 19:36:35 GMT 1996 Wind has shifted and is coming from the West now, the seeing was good all morning (SE winds) until now. LOW-L COMMENT: Sat Apr 20 19:37:35 GMT 1996 Paused the program to troubleshoot the CTS10 board and the system clock. Removed L00383 from drive #0 and eventually will start up with L00384 in drive #0 and L00385 in drive #1. MKIII COMMENT: Sat Apr 20 20:13:19 GMT 1996 Shutting down to allow work to be done on the CHIP. CHIP--CHIP--CHIP--Sat Apr 20 21:16:05 GMT 1996 ending tape W-L COMMENT: Sat Apr 20 21:18:00 GMT 1996 out that the only time the computer system clock gets set by the CTS10 board is when the computer is rebooted. We may need to create an interrupt handler to fix the problem. Restarted system with tapes as mentioned in the laast lowl message. Comment--Sat Apr 20 21:21:28 GMT 1996 Activity report: Didn't get coordinates for prominences because we didn't run the dPMon today. No coronal activity.
