Fynbo,\nDaniele Malesani (DARK/NBI), Dong Xu (Weizmann Inst.),\nand Pall Jakobsson (Univ. Iceland), report on behalf\nof a larger collaboration:\n\nWe observed the field of GRB 100802A (Troja et al., GCN 11031, Siegel\n& Troja, GCN 11032) with the NOT equipped with ALFOSC. Observations\nwere carried out with mean time Aug 11.10 UT (212.7 hr after the GRB).\n\nThe object seen in our early-time NOT image (Xu et al., GCN 11042) is\nbarely detected in the new stacked image, and has decayed by 1.3 +/-\n0.4 mag between the two epochs.\n\nWe note that the NOT object is slightly offset (by ~1.1\" W) with\nrespect to the UVOT position (GCN 11032; also confirmed by P60\nimaging; B. Cenko, priv. comm.). Coupled to the slow decay, this may\nindicate the presence of an underlying constant source of light, which\ncould be the host galaxy or a foreground, unrelated object.\n\nAn image showing the two epochs is available at the following URL:\n\nhttp://www.astro.ku.dk/~malesani/GRB/100802A/GRB100802A_epoch2.jpg\n\nGiven the relative brightness of the underlying source (R ~ 23.7), we\nencourage further photometric and spectroscopic observations.\n\n[GCN OPS NOTE (12aug10): Per author's request, MC was added to the author list.]",
