The Time Domain Spectroscopic Survey (TDSS)
4-6 Year Optical Spectroscopic Survey already begun 260,000 spectra of variables selected from PanSTARRs science pathfinder for LSST and other TD imaging surveys piggybacks on SDSS IV eBOSS survey covers ~7500 deg2 of sky to i~21.5mag 90% will be discovery spectra Science on brown dwarfs, eclipsing binaries, CVs, RRLyr, Quasars Students welcome!

Most variable objects range across the full color plane.

Spectra probe a wide range of astrophysics.

TDSS Few Epoch Spectroscopy
~10,000 second epoch spectra for spectroscopic variability probes activity in late-type Main Sequence stars, and dM/WD binaries 'HyperVariable' stars and quasars BAL trough variability in quasars double-peaked emitters (z<0.8) quasar broad H variability (z<0.8) RV variations in dwarf carbon stars
