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

A night fraught with technical problems and very variable seeing. Autocollimator and slitmask problems lost us a fair amount of time early in the night. RSS was out of action for most of the night, after which we observed a number of HRS blocks of varying priority.

Science data taken for:
2020-1-MLT-002 P1 HRS (HRS study of long-period eclipsing binaries)
2021-1-MLT-005 P1 HRS (x2) (Tracing the history of extreme helium stars)
2020-2-MLT-009 P2 HRS (x3) (Spectroscopic monitoring of candidate white dwarf + Be star binaries.)
2021-1-SCI-015 P2 HRS (Measuring the orbits of double white dwarfs. @_sublunar_)
2021-1-SCI-013 P2 HRS (x3) (Constraining the nature of companions in massive single-lined spectroscopic binaries)
2018-2-MLT-005 P2 RSS (Probing the winds from massive binary star supernova progenitors)
2021-1-SCI-034 P2 SCAM (Finding the binary responsible for an old Nitrogen Nebula)
2021-1-SCI-011 P3 HRS (High-Velocity Interstellar Absorptions)
2021-1-SCI-007 P3 HRS (Probing the binarity of a sample of galactic proto-planetary nebulae)
2021-1-SCI-002 P3 HRS (x2) (Observations of new roAp stars @dlhwp)
