I.A. Smith (Rice U.), D.A. Perley (LJMU), and N.R. Tanvir
(U. of Leicester) report:
We observed the Swift UVOT location of GRB 210104A (Troja
et al., GCN Circ. 29233) using the SCUBA-2 sub-millimeter
continuum camera on the James Clerk Maxwell Telescope. The
observation started at 08:23 UT on 2021-01-05, with the
mid-point of the run at 0.894 days after the burst trigger.
Exposures totaling 1.0 hours were made in very good weather
conditions. No source was detected, with the RMS background
noise being 1.7 mJy/beam at 850 microns and 14.5 mJy/beam
at 450 microns.
We thank Kevin Silva, Mark Rawlings, and the JCMT staff for
the prompt support of these observations that were taken under
project M20BP026.
