N2 - We report on the mass and distance measurements of two single-lens
events from the 2015 Spitzer microlensing campaign. With both
finite-source effect and microlens parallax measurements, we find that
the lens of OGLE-2015-BLG-1268 is very likely a brown dwarf (BD).
Assuming that the source star lies behind the same amount of dust as the
Bulge red clump, we find the lens is a 45 ± 7 {M}{{J}}
BD at 5.9 ± 1.0 kpc. The lens of of the second event,
OGLE-2015-BLG-0763, is a 0.50 ± 0.04 {M}⊙ star
at 6.9 ± 1.0 kpc. We show that the probability to definitively
measure the mass of isolated microlenses is dramatically increased once
simultaneous ground- and space-based observations are conducted.
