To identify and characterize the Sun's neighbors, we propose to obtain red spectra (5300-9900+ Å) for suspected nearby red, brown, and white dwarfs. These spectra play an important role in a new parallax effort initiated as part of a small telescope consortium operating at CTIO. This new effort, CTIOPI2, will be an expansion of the highly successful CTIOPI effort - an NOAO Surveys Program in which we are measuring parallaxes for more than 200 southern nearby stars. Both are carried out under the RECONS (Research Consortium on Nearby Stars) effort based at Georgia State U., Johns Hopkins U., and U. Virginia. During RECONS' two previous CTIO spectroscopic observing runs, we had two partly cloudy nights in Feb 1998, and three rainy nights in Jul 2001. Nonetheless, from the earlier run's meager data we have identified six new stars within 25 pc, two of which lie within 10 pc. High quality spectra for these new nearby stars are being provided to the fundamental database of the NASA/NSF NStars Project. This proposal is similar to our previous proposal, 2001A-0270, although we now include three new samples of stars that are being examined for CTIOPI2 targets. These samples are being used for both PhD (Jao, Subasavage) and undergraduate senior (Bean, Walkowicz) theses.
