  We report the detection of a compact (of order 5 arcsec; about 1800 AU
projected size) CO outflow from L1148-IRS. This confirms that this Spitzer
source is physically associated with the nearby (about 325 pc) L1148 dense
core. Radiative transfer modeling suggests an internal luminosity of 0.08 to
0.13 L_sun. This validates L1148-IRS as a Very Low Luminosity Object (VeLLO; L
< 0.1 L_sun). The L1148 dense core has unusually low densities and column
densities for a star-forming core. It is difficult to understand how L1148-IRS
might have formed under these conditions. Independent of the exact final mass
of this VeLLO (which is likely < 0.24 M_sun), L1148-IRS and similar VeLLOs
might hold some clues about the isolated formation of brown dwarfs.
