MDM Observatory 1.3m Telescope Observing Report for 2022 Jan 06 Observer(s): Qiong Li Institution(s): UMICH Instrument: Echelle Worked for 6 hours (all night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Seeing 0.4 arcsec, Clear, Winds Calm Mid: Seeing 0.4 arcsec, Clear, Winds Calm End: Seeing 0.4 arcsec, Clear, Winds Calm Observing Summary: The sky is clear with a seeing of ~0.4''. But we met a problem at midnight: the readout time was too short when the fit file was written (~1.12sec). The output image looks wrong. Most of pixels are zero. I restarted Owl software and we lost the connection to Owl, it shows: 'ERROR - Driver PCI Device 0 failed to open ERROR - ( CArcPCI::Open() ): Failed to open device ( /dev/astropci0 ) : ( errno: 16 ) - Device or resource busy'. I tried an exposure. It shows an Error as: 'ERROR - Not connected to any controller!' Then, I followed the solution of Eric: click 'Setup' -> 'Apply'. Then it shows another Error as: 'ERROR - SetupThread error: java.lang.Exception: Not connected to any device!' Justin rebooted the mdmarc2 and restarted Owl software. Then we tried an exposure. But the readout time is still not correct (too short, ~2 sec). Justin has tried reseating the fiber connections, rebooting mdmarc2, restarting owl, and power cycling the ccd electronics. They all didn't work. ------------------------------ Submitted on 2022 Jan 7 [4:13:31]
