Servillat (Harvard) report:\n\n\"We observed the location of the short GRB 100702A (GCN 10916) with\nthe PANIC infrared imager on the Magellan/Baade 6.5-m telescope\nstarting on 2010 July 2.089 UT (65 min after the burst).  A total of\n27 min were obtained in the J-band with seeing of about 0.55 arcsec.\nWithin the 2.4-arcsec radius XRT error circle we detect one bright\npoint source and two fainter sources at the following coordinates\n(J2000; astrometry relative to the 2MASS catalog):\n\nS1: RA = 16:22:47.23, DEC = -56:31:55.6\nS2: RA = 16:22:47.53, DEC = -56:31:54.6\nS3: RA = 16:22:47.24, DEC = -56:31:52.2\n\nSource S1 is the same as source \"B\" in GCN 10918 (Malesani et al.),\nwhile sources S2 and S3 are not detected in their finder.\n\nWe note that in 2MASS images of the field source S1 is possibly\nblended with the bright star at RA = 16:22:47.01, DEC = -56:31:53.5\n(designated source \"A\" in GCN 10918), while sources S2 and S3 are\nbelow the 2MASS sensitivity threshold.\n\nAdditional observations are planned to check for variability of\nsources S2 and S3.\"",
