Using the Infrared Array Camera and the Multiband Imaging Photometer
and Spectrometer aboard the Spitzer Space Telescope, we have obtained
photometry for Lupus 3, one of the clouds comprising the Lupus star
forming complex in the Scorpius-Centaurus OB association.  We
recovered 3.6 micron, 4.5 micron, 5.8 micron, 8.0  micron, and 24
micron photometry for 81 known sources in our field of view, as well
as hundreds of previously unidentified sources.  Using selection
criteria based on the similar Spitzer photometric work in Taurus of
Luhman et al 2006, we selected 8 new Lupus 3 member candidates.  We
obtained low resolution spectra on the 6.5m Magellan telescope of 6
candidate members.  All six objects are confirmed as young,
disk-bearing sources with emission features indicative of active
accretion.  We discuss the usefulness of such a sample of nearby young
cluster members for detailed follow-up observations of low-mass star
and brown dwarf circumstellar disks and multiplicity studies.
