Myungshin Im, Changsu Choi, Hyunsung Jun, Eugene Kang (CEOU/Seoul
National University), Y. Urata (NCU), P. Choi (Pomona College),
T. Sakamoto (NASA/GSFC), and N. Gehrels (NASA/GSFC) on behalf
of a larger collaboration
Using UKIRT, we obtained multiple sets of zYJHK images of GRB 100906A
(Markwardt et al. GCN 11227) with a series of z, Y, J, H, and K filters
using UKIRT. The observation started at Sept. 06, 14:23 UT or roughly 34
minutes after the BAT alert.
We clearly identify an uncatalogued source in images in all the filters.
The preliminary magnitude of the afterglow is J= 14.93 +- 0.02 and
K=13.54 +- 0.02 (Vega), calibrated against 2MASS stars in the vicinity.
