LOW-L COMMENT: Thu Jul 23 17:09:40 GMT 1998 L00533 popped out of Test drive #1 as it should have. I cleaned the drive and installed L00535. MKIII COMMENT: Thu Jul 23 17:31:59 GMT 1998 Moving the tilt plate in and out to see if there is a change in the darker regions visible in the scans. **MKIII PROBLEM**: Thu Jul 23 17:33:06 GMT 1998 Regarding the darker regions visible in the scans in the NNW and SSW, I don't see it in the realtime scans, but I do see the darkness in the Xanim window showing the time-lapse sequence. Are these images treated differently, is one calibrated while the other isn't? Could something in the calibration be causing the problem? **MKIII PROBLEM**: Thu Jul 23 17:38:44 GMT 1998 I just moved the Dark Shutter in and out to see if the Xanim images change. There was no change after moving the tilt plate in and out.

I don't see anything that could be causing the darkness problem. It must be something beyond the slits or else its a calibration or electronic problem. **MLSO PROBLEM**: Thu Jul 23 18:33:32 GMT 1998 The network connection to Boulder works now. One of Alice's message's mentioned some kind of security test going on over there.

MKIII COMMENT: Thu Jul 23 20:01:15 GMT 1998 **MKIII PROBLEM**: Thu Jul 23 20:01:31 GMT 1998 I checked the occulting disk focal plane more closely and I can see what may be vignetting in the image there, or it may be that a reflection from the back of the O1 is not concentric with the occulting disk. It is difficult to see since the light is faint and right next to the intense light reflecting off the occulting disk. I'll investigate further.

I tried tilting the O1 about 10 minutes ago but didn't see any change at the occulter or on the scans. The lift has run out of battery energy so I am charging it right now. **** EVENT COMMENT ****: Thu Jul 23 22:37:51 GMT 1998 Possible small CME at PA=110 starting at aroung 1945 ut. **MKIII PROBLEM**: Thu Jul 23 22:43:24 GMT 1998 The lift won't charge up fast enough for me to use anymore today. The next things to check would be tilt and rotation of the O1 to see if the dark regions of the scan move with the O1. We know that the occulting is good and that the optics beyond the slots are probably good. We also know that there is a reflection (probably) of some type visible at the occulter. There is also a lot of Cetral American smoke in the air, it has been around since last week at least.
