  Multi-wavelength monitoring of Sgr A* flaring activity confirms the presence
of embedded structures within the disk on size scales commensurate with the
innermost accretion region, matching size scales that are derived from observed
light curves within a broad range of wavelengths. We explore here a few of the
observational signatures for an orbiting spot in non-keplerian motion near the
event horizon of Sgr A* and model light curves from plunging emitting material
near the marginally stable orbit of Sgr A*. All special and general
relativistic effects (relativistic beaming, redshifts and blue-shifts, lensing
effect, photon time delays) for unpolarized synchrotron emission near a
Schwarzschild and Kerr black hole are all taken into consideration.
