General Description

This program is designed to detect interstellar Li I 6707 absorption from
 the interstellar medium of the SMC toward the star AV456 (Sk143).  We require S/N~400
 to provide limits that will constrain the origin of Li, including both primordial
 and galactic contributions.  We will use UVES with Dichroic#2 and an 0.7" slit to
 obtain R~60,000 spectra covering both Li I and other ions useful for constraining
 the ionization conditions of the gas (e.g., Ca I and II).  We have broken the exposures
 up into 10 ~57 minute blocks.

Critical Observing Condition Constraints

We request sub-arcsecond seeing for the best throughput.  Ideally seeing
 of 0.8" or better would be used.  Although we can observe through thin cirrus, clearer
 skies would be beneficial.
