Frail (NRAO) report:\n\nWe observed the location of GRB 130131A (Grupe et al., GCN Circ. 14156) \ntwice using the SCUBA-2 sub-millimeter continuum camera on the James \nClerk Maxwell Telescope.  The first observation started at 14:36 UT on \n2013-01-31, corresponding to 40 minutes after the burst trigger.  It \nlasted 2.0 hours in good weather conditions.  The second observation \nstarted at 12:40 UT on 2013-02-01, corresponding to 0.95 days after \nthe burst trigger.  It lasted 2.1 hours in good weather conditions.  \nNo source was significantly detected in the individual or combined \nobservations at the VLA location (Laskar et al., GCN Circ. 14171).  \nThe combined RMS was 2.2 mJy/beam at 850 microns and 18.2 mJy/beam at \n450 microns.\n\nWe thank Iain Coulson, Jim Hoge, Callie McNew, Alexander Karim, and \nWilliam Montgomerie for their prompt support of these observations.",
