We observed the counterpart to GRB 120422A (Troja et al., GCN Circ.
13243) using the SCUBA-2 sub-millimeter continuum camera on the James
Clerk Maxwell Telescope.  The observation started at 07:53 UT on
2012-04-22, corresponding to 41 minutes after the burst trigger.
Exposures totaling 1.5 hours were made in moderate weather conditions.
No source was detected, with a preliminary RMS of 2.8 mJy at 850 microns.

We thank William Montgomerie for his prompt support of these observations.
