D. A. Perley (UC Berkeley) and C. Melis (UCLA) report:
On the night of 2008-07-10 starting at 10:32:30 UT, we began a series of
IR exposures with the Lick Shane 3 meter telescope, equipped with the
GEMINI IR imager. We acquired imaging in J and K' filters
simultaneously between 10:32 and 10:44. We returned to the field during
morning twilight and took additional imaging between 12:19 and 12:25 in
H and K' simultaneously.
Calibrating to two nearby 2MASS stars, we estimate a preliminary
magnitude in the first epoch J-band imaging of:
J = 16.24 +/- 0.05
between 10:32 and 10:44 (mid-time of 206 minutes after the GRB.)
The GRB afterglow displays tentative evidence of brightening over the
exposure period. Additional analysis is ongoing.
