SpectraBot is a new
50-inch automated telescope located 16 miles north of campus at the
Morgan-Monroe Station of the
Goethe Link Observatories. It will be devoted to automated
long-term monitoring (both CCD imaging and spectroscopy) of
time-variable sources. The telescope is now (2005) undergoing
commissioning.
