Fri Apr 27 21:03:36 GMT 2001 CHIP Start Patrol COMMENT: Fri Apr 27 21:03:33 GMT 2001 Slits were adjusted and tophat reinstalled in MK4. Guiding. Resuming observations with CHIP and PICS. Testing MK4. **MKIV PROBLEM**: Fri Apr 27 21:04:46 GMT 2001 When removing the tophat, we found that the red mark on the encoder gear tooth was not aligned with the red-marked gear tooth on the tophat. Alignment was off by two teeth. David estimated that this misalignment could be the 9.5 degree misalignment between features seen on LASCO and PICS and the features seen on MK4. Teeth were properly aligned when reinstalling tophat. **MKIV PROBLEM**: Fri Apr 27 21:08:44 GMT 2001 Barrel limits are now 94.68 CW and 285.35 CCW before this adjustment limits were about 91 CW and 282 CCW. -- david Fri Apr 27 21:23:15 GMT 2001 MKIV Start Correct Fri Apr 27 21:23:36 GMT 2001 PICS Start Patrol Fri Apr 27 21:25:05 GMT 2001 MKIV End Correct Fri Apr 27 21:26:31 GMT 2001 MKIV Start Correct Fri Apr 27 21:28:19 GMT 2001 MKIV End Correct Fri Apr 27 21:29:21 GMT 2001 MKIV Start Patrol **** EVENT COMMENT ****: Fri Apr 27 21:29:32 GMT 2001 Possible EPL at PA 122, RV ~1.3.
