  The Profiler of Moon Limb is a recent instrument dedicated to the monitoring
of optical turbulence profile of the atmosphere. Fluctuations of the Moon or
the Sun limb allow to evaluate the index refraction structure constant C_n^2(h)
and the wavefront coherence outer scale L_0(h) as a function of the altitude
$h$. The atmosphere is split into 33 layers with an altitude resolution varying
from 100m (at the ground) to 2km (in the upper atmosphere). Profiles are
obtained every 3mn during daytime and nighttime. We report last advances on the
instrument and present some results obtained at the Plateau de Calern (France).
