APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 28, 2026 (SJD 61159) ---- Observing Team ---- Audrey Oravetz ---- Observing Plan ---- Tue 28 Apr 2026 61159 0.94 02:40 02:56 11:04 10:21 18:30 --- bright ( 9.2 h, w/ 1.1 h for 8 deg design) ---- Observing Summary ---- The night was lost due to thick clouds. We never opened. ---- Software Issues ---- The FPI shutter was found in an unknown position after starting the eveningcals during afternoon checkout. I also had a bit of trouble logging into the APOGEE FPI machine, but once I was able to, I restarted the FPI screen that was found killed. Tonight's morningcals should be back to normal. ---- Observing Log ---- Afternoon: ========== 21:02:09 boss exposure 0.0, file=400609 21:03:29 boss exposure 20.0, file=400610 21:07:46 boss exposure 4.0, file=400611 21:08:26 boss exposure 4.0, file=400612 21:09:09 sp1.motor.move= -1113, -1113, -1111 21:09:09 Hartmann collimate output sp1: offset: r= -1649 (Out of focus); b= 1.8 (In Focus) sp1: pred. move: spAverageMove= -1113 sp1: pred. resid: r= -535, b= -1.7, txt= OK, spTemp = 5.4 21:14:09 boss exposure 4.0, file=400613 21:15:39 boss exposure 25.0, file=400614 ******************************************************** 21:17:24 Field-Design-Configuration: -999--999-26321 ******************************************************** 21:18:01 FVC LOOP AND BOSS CALS fvc_rms= 38.04 fvc_deltarms= 32.28 fvc_filename=/data/fcam/61159/fimg-fvc1n-0001.fits fvc_perc_90= 52.30 fvc_percent_reached= 1.80 fliswarm talk -c gfa expose --bias --count 10 fliswarm talk -c gfa expose --dark --count 5 5 fliswarm talk -c gfa expose --flat 1 jaeger configuration random --danger The FPI shutter failed to respond during the beginning of the eveningcal sequence. I stopped it in order to deal with the shutter, and then restarted it. The eveningcal sequence operated without the FPI working, until the connection was re-established and the last two FPI images were taken manually. 21:04:34 hal.hal 176560 apogeefpi e error="Open shutter failed with error code 255: packet_write_wait: Connection to 192.168.2.160 port 22: Broken pipe\r\n" 21:04:34 hal.hal 176560 apogeefpi f shutter_position=? 21:04:34 CmdDone: hal.hal 176560 apogeefpi close Server says "message:Apogeefpi_notconnected" (pytims) apogee@apogeefpi:~/APOGEEtims/log$ tail tims_server.log 2026-04-29T01:12:26.326477 [__main__.TIMSServerFactory] New connection from IPv4Address(type='TCP', host='127.0.0.1', port=36608) 2026-04-29T01:12:26.326854 [TIMSServerProtocol,11300,127.0.0.1] Client Registered: Cli3147303 2026-04-29T01:12:26.326949 [TIMSServerProtocol,11300,127.0.0.1] Received: Sender:Cli3147303, Subsystem:Apogeefpi, Command:['shutters', 'low1'] 2026-04-29T01:12:26.326997 [TIMSServerProtocol,11300,127.0.0.1] Sending Cli3147303: "Server Cli3147303 message:Apogeefpi_notconnected" 2026-04-29T01:12:26.327459 [TIMSServerProtocol,11300,127.0.0.1] Unregistering Client: Cli3147303 2026-04-29T01:15:50.347244 [__main__.TIMSServerFactory] New connection from IPv4Address(type='TCP', host='127.0.0.1', port=36612) 2026-04-29T01:15:50.347631 [TIMSServerProtocol,11301,127.0.0.1] Client Registered: Cli3147411 2026-04-29T01:15:50.347727 [TIMSServerProtocol,11301,127.0.0.1] Received: Sender:Cli3147411, Subsystem:Apogeefpi, Command:['shutters', 'high1'] 2026-04-29T01:15:50.347808 [TIMSServerProtocol,11301,127.0.0.1] Sending Cli3147411: "Server Cli3147411 message:Apogeefpi_notconnected" 2026-04-29T01:15:50.348463 [TIMSServerProtocol,11301,127.0.0.1] Unregistering Client: Cli3147411 Re-established the connection through the apogeee-ics machine. 01:10Z - Started ventilating.
