D. A. Perley (Caltech) reports:
I observed the location of GRB 130215A (D'Elia et al., GCN 14204) with
the Wide-Field Infrared Camera (WIRC) on the Palomar 200-inch telescope
on 2013-02-16 UT between 02:14 and 03:17. A series of nine 60-second
images each were taken in Ks, J, and H filters, followed by a second
series in Ks. High winds were present and seeing significantly degraded
over the course of the observations.
The optical/NIR afterglow (Zheng et al., GCN 14205, Covino et al., GCN
14211) is well-detected in a preliminary reduction of the Ks-band
images. Photometry (calibrated relative to 2MASS standards in the
field) gives the following magnitudes:
t_mid=24.89 hours : Ks = 17.23 +/- 0.05 mag (19.07 AB)
t_mid=25.65 hours : Ks = 17.34 +/- 0.08 mag (19.18 AB)
Further observations are planned.
