We present SMA observations of GRB151027A with multi-wavelength data
set. The event was the 999th GRBs detected by the Swift satellite and
it has a dense afterglow monitoring from X-ray, optical, to radio band.
Our SMA observations was started at ~2 days after GRB
trigger and identified the bright (~17 mJy) submm afterglow. The
rapid decay with the index ~-2 indicates reverse shock synchrotron
radiation or jet phase was dominated during the SMA observational
period. We also reduced VLA monitoring data and performed a
two-dimensional relativistic hydrodynamic jet simulation to describe
the radio afterglow.
