SCUBA is a new sub-millimeter instrument on the James Clerk Maxwell
Telescope.
It can use two arrays of bolometers to simultaneously map the same patch
of sky (approx 2.3 arcmin in diameter) at 850 and 450 microns.
The field of view and sensitivity make it a good instrument to use
in the sub-millimeter on arcminute sized gamma-ray burst error boxes.
For well-localized radio and optical counterparts, sensitive pointed
observations can be made using the central pixel of these arrays, or
using the dedicated photometry pixels at 1100, 1350, and 2000 microns.
We have an ongoing program of Target of Opportunity GRB observations.
As a test run, we observed GRB 970508 on May 26 using the 1350 micron
pixel.
No sources were detected, consistent with other millimeter observations.
