GCN 15516),\nusing CQEUAN (Park et al. 2012) on the 2.1-m Otto-Struve telescope \nat the McDonald Observatory in Texas, US. The observation started \nat 2013-11-29 01:31:43 UT, or about 1.63 days after the BAT alert. \nA series of images were taken in r, i, and z-band for about 45 min.\n\nWe identify the red source reported in Butler et al. (GCN 15525), but\nno significant fading of the source was found with z = 21.90 +- 0.15 AB mag,\nconsistent with Z = 21.85 +- 0.16 mag from Butler et al. (GCN 15525).\nThis suggests that the red source may not be the GRB afterglow,\nor the light curve is changing very slowly.",
