Signal is seen in the raw kcor images. However signal is not easily associated with promiances in Gong Halpha as we would normally expect. CME detction code suggests this is an on going erruption; but by eye no eveloution in the enhancment is obvious over the 30 minutes of data already taken. ___end___ ****EVENT COMMENT BY berkey**** : Fri Oct 06 17:58:15 GMT 2017 Enhancement is also visible in the CoMP 1079 raw data. ___end___ GENERAL COMMENT BY berkey: Fri Oct 06 18:24:52 GMT 2017 SGS is seeing peroidic shakes/oscillations of about +/- 40 arcseconds that take about 4 seconds to dampen. They look a lot like earthquakes. Not sure if the guider is following an aersol or there is some mechanical issue. ___end___ GENERAL COMMENT BY berkey: Fri Oct 06 18:30:15 GMT 2017 SGS "earthquake" appears to have a BIG RA error corrspondign with a Big Dec control movement. ___end___ GENERAL COMMENT BY berkey: Fri Oct 06 18:37:42 GMT 2017 Visual/auditory inspection of the dome found the closed loop Hepa had a large vibration with peroidic big jerky jumps. I assume there is something wrong with the ciruclation fan in the Hepa box itself. However with the intersting west limb feature; the Closed loop hepa was shut down, and no attempts to troubleshoot the source of the hepa vibration will be made until the feature passes. ___end___ Fri Oct 06 19:59:17 GMT 2017 KCOR End Patrol Fri Oct 06 19:59:36 GMT 2017 COMP End Patrol Fri Oct 06 20:00:16 GMT 2017 CoMP occulter has been re-centered Fri Oct 06 20:00:20 GMT 2017 COMP Start Patrol on cookbook: waves-00001.cbk Fri Oct 06 20:01:08 GMT 2017 Kcor Focus/alignment program exited Fri Oct 06 20:07:17 GMT 2017 KCOR Start Synoptic Patrol Fri Oct 06 21:31:25 GMT 2017 KCOR End Patrol Fri Oct 06 21:31:28 GMT 2017 COMP End Patrol Fri Oct 06 21:32:45 GMT 2017 SGS Alignment complete Fri Oct 06 21:33:09 GMT 2017 CoMP occulter has been re-centered Fri Oct 06 21:33:50 GMT 2017 Kcor Focus/alignment program exited Fri Oct 06 21:35:19 GMT 2017 COMP Start Patrol on cookbook: waves-00001.cbk Fri Oct 06 21:35:54 GMT 2017 COMP End Patrol Fri Oct 06 21:35:55 GMT 2017 COMP Start Patrol on cookbook: synoptic-00010.cbk Fri Oct 06 21:36:33 GMT 2017 KCOR Start Synoptic Patrol Sat Oct 07 00:11:39 GMT 2017 KCOR End Patrol Sat Oct 07 00:17:29 GMT 2017 COMP End Patrol Sat Oct 07 00:17:30 GMT 2017 COMP Start Patrol on cookbook: waves-00001.cbk Sat Oct 07 00:56:58 GMT 2017 CoMP Paused for clouds Sat Oct 07 01:00:18 GMT 2017 CoMP Restarted from pause Sat Oct 07 01:00:18 GMT 2017 COMP End Patrol **CoMP PROBLEM COMMENT BY berkey** : Sat Oct 07 02:08:37 GMT 2017 Found the CoMP O1 position was reporting at -0.1mm. This appears to be incorrect reporting. O1 was in its nonimal position not at the end of the range during cleaning this morning. Running the UComp - Reset O1 motor.vi cleared up the problem. ___end___ GONG COMMENT BY berkey: Sat Oct 07 02:10:13 GMT 2017 Gong had its pitch errors again this morning until about 10am. Using the gong expert to stop the pitch motor for about 1 minute seemd to stop it form shaking. ___end___ **KCOR PROBLEM COMMENT BY berkey** : Sat Oct 07 02:14:09 GMT 2017 Closed loop (sunward) hepa, needs a new circulating fan. After observing today the hepa filters were tempoarly removed to give access to the motor. When on the motor was louder than accecpted with large jumps/noises ever 30 seconds. The hepa will remain off until the motor is replaced/fixed/etc. ___end___
