Rau\n(Caltech) report on behalf of a larger collaboration:\n\nWe have imaged the field of GRB080319B (Racusin et al., GCN 7427) with the\nblue filter (15.8 um) of the IRS peak-up camera on board the Spitzer Space\nTelescope.  Observations consisted of 60 pointings, each with two dithered\n30 s cycles, beginning at March 21.81 UT (~ 2.55 d after the burst).  At\nthe location of the optical afterglow, we measure a flux density of 35.7\n+/- 3.9 uJy.\n\nWe wish to thank the entire Spitzer team for the prompt execution of these\nobservations.",
