Summary

A good dark night with mixed but overall reasonable seeing. We did some high priority blocks, including two P0s. Some technical downtime with a database crash that caused us to lose a long block.

Science data taken for:
2017-2-SCI-049 P0 RSS (SALT spectroscopic follow-up of supernova candidates for further investigations of dark energy)
2017-2-DDT-002 P0 RSS (High-quality spectroscopy to confirm the record-low metallicity of a LSB in a nearby void)
2016-2-MLT-005 P1 HRS (Investigating the chemical composition of bright star beta Pic and its nearby circumstellar material)
2017-1-MLT-014 P1 RSS (Measuring redshifts for galaxies in the MeerKAT LADUMA survey)
2017-2-SCI-013 P1 HRS (On the orbital period of a roAp star @dlhwp)
2017-2-SCI-045 P1 RSS (Confirmation and redshift determination of galaxy clusters.)

SO: Veronica
Others: Fred & Enrico on DIMM. Johan & Timmy to fix the Dome Shutter bearing

----------------------------------------------------------------------
Summary
----------------------------------------------------------------------


We started the night with a Dome Shutter bearing that broke as we attempted to open and the Technical stand-by guys did a tremendous job to get us on sky with only 2 hours lost. The rest of the clear night was marred by terrible seeing, so only low priority blocks were done.

Science data taken for:
2017-2-SCI-030 P3 HRS (Metal-Poor Subdwarfs for Stellar Modeling Calibration)
2017-1-MLT-005 P3 HRS (x5) (Spectroscopic investigations of Cepheids and stars belonging to open clusters and associations)

Summary

Mostly clear night with good seeing. Lost 2 hours to an unfortunate technical problem on the Calibration System (used for all Low Resolution Spectrograph observations) that the Technical crew will have to attend to tomorrow. Luckily the DDT observation was successfully done early in the evening and also very fortunately we could continue with the High Resolution Spectrograph for the rest of the night.

Science data taken for:
2017-2-DDT-002 P0 RSS (High-quality spectroscopy to confirm the record-low metallicity of a LSB in a nearby void)
2017-2-SCI-056 P1 RSS (Measuring Galaxy Kinematics For Construction of the Velocity Function)
2017-2-SCI-017 P2 HRS (HRS observations of symbiotic stars)
2017-2-SCI-022 P3 HRS (Measuring the interstellar abundance of lithium in the Large Magellanic Cloud)
2017-2-SCI-030 P3 HRS (x3) (Metal-Poor Subdwarfs for Stellar Modeling Calibration)
