Subject: 2.5m obslog 20131024 (MJD 56590) From: gebelke@apo.nmsu.edu Date: Fri, 25 Oct 2013 11:27:35 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday October 24, 2013 (MJD 56590) ---- Observing Team ---- Kaike Pan Garrett Ebelke Jon Brinkmann (afternoon) Dan Long (phone support) French Leger (phone support) ---- Observing Plan ---- 24 Oct 2013 56590.0 0.60 01:28 12:07 20:39 07:20 BOSS until 04:51 (3.4 h), then APOGEE (7.6 h) ---- Observing Summary ---- Half of the night was lost due to radar returns, eventually followed by some rain and a little hail. We observed the following plates: Cart 8, 6956 - 2x ABBA - Missing: 35, 184 - Faint: 88 Cart 11, 6138 - Cart 10, 7148 - Cart 7, 7071 - 2x ABBA Sequences - Missing: None - Faint: 188, 197, 270 Cart 9, 5604 - 1x AB - Missing: None - Faint: 99, 133, 284 On arrival, the 2.5m info on the weather page information was not visible. JonB looked into the matter and was able to fix. During afternoon checkout, the rotator would not slew, and there was a red light on the rotator glentek amplifier (reverse inhibit). See Problems in detail. ---- Observing Log ---- Afternoon: ---------- BOSS collimation check: COLLIMATE: Camera b1 appears to be IN-FOCUS (|mean| 0.15 pix) COLLIMATE: Predict blue camera ring movement of 5.0 degrees for spectro-2 COLLIMATE: Predict (red) piston movement of 128 steps for spectro-2 COLLIMATE: Issue command: "boss moveColl spec=sp2 a=128 b=128 c=128" COLLIMATE: Predict (red) piston movement of 85 steps for spectro-1 COLLIMATE: Issue command: "boss moveColl spec=sp1 a=85 b=85 c=85" MCP instr = 11 (mounted); Guider cart= 11, plate= 6138, side= A (loaded); ---------- motorPosition sp1: 21663, 21559, 21352; sp2: 22309, 21788, 22790; ---------- Median spectrographs temperatures: Tsp1= 9.7, Tsp2= 9.1; Outside air temperature= 15.5; i UT File/Exp Imtype Nread Dth Ct-Plate Archiv Offset Comment -------------------------------------------------------------------------------- 1 22:06 10280001 Dark 3 A 11-6138 a-b-c - None 2 22:15 10280002 Dark 60 A 11-6138 a-b-c - None 3 22:26 10280003 QuartzFlat 10 A 11-6138 a-b-c - None 4 22:28 10280004 ArcLamp-Thar 12 A 11-6138 a-b-c -0.09 None 5 22:30 10280005 ArcLamp-Une 40 A 11-6138 a-b-c - None 6 22:37 10280006 ArcLamp-Thar 12 B 11-6138 a-b-c 0.38 None 7 22:39 10280007 ArcLamp-Une 40 B 11-6138 a-b-c - None 8 22:47 10280008 Dark 60 A 11-6138 a-b-c - None ----- Night ----- 00:13:19 loadCart: ct=8, pl=6956, sd=A; 00:48:04 sop.gotoField = running; No guide stars, used offsets and found stars. +7dec. 00:54Z - Started 1x ABBA. 9 00:36 10280009 Dark 10 A 8-6956 a-b-c - None 10 00:38 10280010 Dark 10 A 8-6956 a-b-c - None 11 00:56 10280011 Object 47 A 8-6956 a-b-c - None 12 01:04 10280012 Object 47 B 8-6956 a-b-c - None 13 01:13 10280013 Object 47 B 8-6956 a-b-c - None 14 01:21 10280014 Object 47 A 8-6956 a-b-c - None 15 01:29 10280015 Object 47 A 8-6956 a-b-c - None 16 01:38 10280016 Object 47 B 8-6956 a-b-c - None 17 01:46 10280017 Object 47 B 8-6956 a-b-c - None 18 01:54 10280018 Object 47 A 8-6956 a-b-c - None 19 02:03 10280019 DomeFlat 5 A 8-6956 a-b-c - None 20 02:05 10280020 Dark 10 A 8-6956 a-b-c - None 21 02:07 10280021 Dark 10 A 8-6956 a-b-c - None flat= /data/apogee/utr_cdr/56590/apRaw-10280019.fits master= /home/observer/bin/apRaw-03720068.fits nfibers= 300 average ratio= 0.750666658667 missing fibers (flat/master 42.69 [above 0.50] --------------------------------------------------------------- ----- 04:02:38 loadCart: ct=10, pl=7148, sd=A; 04:02:41 sop.gotoField = running; 4:05Z - Hartmanns - 168278-79 04:08:04 hartSp2: r=-446, b=-1.5, txt=OK, sp2Temp = 7.5 04:08:04 sos.sp2AverageMove = 203 04:08:09 sp2.motor.move= 203, 204, 203 04:08:09 hartSp1: r=322, b=1.1, txt=OK, sp1Temp = 7.9 04:08:09 sos.sp1AverageMove = -3486 04:08:18 sp1.motor.move= -3486, -3486, -3484 4:08Z - Cals - 168280-81 GSOGTF.

in Detail ---- While performing the afternoon checkout, we discovered the rotator could not move. At first, we tried power cycling the glentek amplifier, but that did not fix it. Whenever we tried to move the rotator (using mcp or tcc), it would start to slew, then kick out of closed loop. We found that moving it to a positive amount (+60deg), it would slew 3-5 arcminutes and stop. When we slewed negative (-60deg) it would slew 3 degrees, then stop. We contacted French and Dan, as we couldn't get a hold of either one on the first call. French said it sounded like the motor had too much torque. Dan called and said we should try reseating the digital module on the front of the glentek amplifier. After pulling that and reseating it, the reverse inhibit light turned green and we were able to slew again. Dan informed us if it happens again, we should simply swap out the digital module for the spare. For reference, the digital modules can be swapped out, but the analog modules are specific to each amplifier/axis.
