Smith (Rice University) report: \n\nFurther observations of GRB 010222 made using the SCUBA sub-millimeter \ncontinuum bolometer array on the James Clerk Maxwell Telescope now fail \nto significantly detect the counterpart described in GCN #971 and #996.\n\nThe observations, made between 14:54 and 18:05 on 2001 March 2 UT, give \na preliminary 850 micron flux density of 0.7 +/- 1.1 mJy.  A 1-hour \nobservation on the previous night is consistent with this result.\n\nIt thus appears as if the source detected earlier is not the quiescent \nhost galaxy.  Indeed, of the 17 bursts studied with SCUBA to date, that \nhave measured redshifts between 0.707 and 3.4, no conclusive detections\nof quiescent sub-millimeter hosts have so far been found (Smith et al. \n1999, A&A, 347, 92; Smith et al. 2001, A&A, in press).\n\nAt least at 850 microns, GRB 010222 may be similar to GRB 980329, \nwhich also had an apparent excess in the SCUBA observations and whose \nsub-millimeter flux decayed rapidly with time (unfortunately, the first \nSCUBA observations were not made until 7 days after that burst).\n\nA final SCUBA observation of GRB 010222 is planned during the coming week.",
