Cenko (UC Berkeley) report:\n\nWe re-observed the field of GRB 100526A (Vetere et al., GCN 10797) with \nNIRI on Gemini-North between 08:30 and 09:00 UT on 2010-06-24 UT.  We \nacquired 27 images of 60 seconds each in K-band.\n\nComparison to our previous K-band imaging of this field (Perley et al., \nGCN 10806) shows the infrared counterpart to have faded significantly. \nA source is still detected at high significance at the afterglow \nposition.  Using the same 2MASS reference star as for our previous \nepoch, we measure a magnitude of:\n\nK = 21.2 +/- 0.2   (t_mid = 27.7 days)\n\nThis corresponds to a decay index (t^-alpha) of only alpha~0.5 from our \nprevious epoch, which is much slower than expected for a late-time \nafterglow, and suggests that the current epoch is likely host-galaxy \ndominated.\n\nA comparison image is posted to:\nhttp://lyra.berkeley.edu/~dperley/100526a/100526a_niri.png",
