Bohyun Observatory\n  in Korea.\n\n    The observation started at 2011 March 31, 14:45:20 UT, and we\n  obtained a series of images in H and K.\n\n    The NIR counterpart is clearly detected in both bands,\n  with the K-band magnitude at 17.29 +- 0.03.\n    Comparison with the K-band magnitude of the same object from\n  the previous night data (Im et al. GCN 11850) shows the dimming\n  of the object by 0.43  mag over one day.\n    The H-band data also show variability, confirming the variability\n  of the source reported earlier (Leval et al. GCN 11854)\n\n    More NIR imaging is planned.",
