E. Berger, R. Chornock, W. Fong (Harvard), W. Krzeminski (LCO), and G.
Anglada (Carnegie/DTM) report:
"We observed the location of the short GRB 100625A (GCN 10884) using the
PANIC infrared imager on the Magellan/Baade 6.5-m telescope on 2010 June
27.39 UT (38.9 hours after the burst). A total of 1.75 hours were
obtained in J-band in good seeing conditions (0.75 arcsec). Within the
refined XRT error circle (GCN 10886) we detect a single object,
coincident with the optical source detected by Levan et al. with Gemini
about 12.3 hours after the burst (GCN 10887). In our combined image the
object appears to be mildly extended. Given the continued detection of
the object about 27 hours after the initial Gemini detection (with r~23
mag), and its extended nature, we consider this source to be a potential
host galaxy."
