The instrument performed well. Alan Diercks observed with Spicam for the first half with good weather and good seeing. Several `ppk error code=168' communication errors occured with the guider and the guider mac crashed once. This did not stop Alan's obserations, but was a nuisance. No other problems to note. Chris Mallauris observed with DIS in low res mode. The weather degraded quickly but improved, generally good conditions for the majority of the run. The telescope and Dis performed well. The guider continued with communication errors and I gave up trying to reset/reboot (only known solution to the particular problem) and guided of the slit. The observations were efficient. I observed two primary targets for the Lens Monitoring program. There was one occurance of the azimuth drive oscillating, but that was surpassed by tracking a magna-sensor.
