It is a small cooling fan on one of the 36979-01 boards inside the ESP300 enclosure. The board with the bad fan is the board that drives the OPAL (slot2). Unfortunately we don.t have spare fan, and the fan is soldered onto the board making it non-trivial to replace. We do have a second 36979-01 board in the ESP300 that is wired to rotate the calibration polarizer (slot1); however we do not use the cal-polarizer (and as far as I remember we have never used it at MLSO). As a temporary fix for the bad fan problem I have removed the bad 36979 from slot 2 and replaced it with the good one from slot 1. The bad 36979 is on the lab bench waiting. A small software change was required to make this work; in the opal move code we check the ESP300 hardware status to see if the opal made it to the commanded position; with the second 36979 remove the magic numbers change from 604/406 (out/in) and to (705/507). With these changes CoMP seems to be working again. . ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Fri Jul 25 21:26:00 GMT 2014 Seeing at least on Kcor seems bad. Looking toward the sun I see a lot of dust particles or bugs. ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Fri Jul 25 22:33:10 GMT 2014 Sky brightness is increasing. ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Fri Jul 25 23:36:33 GMT 2014 Clouds starting to blow up over the observatory. ___end___ Fri Jul 25 23:52:41 GMT 2014 COMP End Patrol Fri Jul 25 23:52:41 GMT 2014 COMP Start Patrol Sat Jul 26 00:06:28 GMT 2014 KCOR End Patrol Sat Jul 26 00:06:28 GMT 2014 COMP End Patrol Sat Jul 26 00:09:11 GMT 2014 COMP Start Patrol Sat Jul 26 00:13:14 GMT 2014 KCOR Start Synoptic Patrol GENERAL OBSERVATORY COMMENT BY berkey: Sat Jul 26 00:59:06 GMT 2014 Clouds passing between the obs and the sun. ___end___ Sat Jul 26 01:29:03 GMT 2014 KCOR End Patrol Sat Jul 26 01:31:21 GMT 2014 COMP End Patrol KCOR COMMENT BY berkey: Sat Jul 26 02:02:50 GMT 2014 I saw some artifacts in the Kcor data so I pulled the O1 to check for bugs (gong's windowed needed "cleaning" today becasue it was covered in insects). No bugs but there was a light dusting of little particles. I blew off the biggest ones. ___end___ Sat Jul 26 02:06:16 GMT 2014: PSPT Abort Patrol
