We have reobserved the field GRB060202 (Fox et al., GCN 4629) with
the Wide Field Camera on UKIRT in K-band filter at a mean epoch of
approximately 5:45 UT on the February 4th.
Our total integration time is 36 min.
We still see the faint source reported by Wang et al. (GCN 4638)
at roughly the same magnitude (K=20.07 in 3" aperture diameter).
We have imaged the same region also with the Low-Resolution
Imaging Spectrometer mounted on the 10-m Keck I telescope.
Observations consisted of 4 x 150 s images taken in the I-band filter
at a mean time about 5:50 UT on February 4th.
The faint source (S1) reported by Cenko et al. (GCN 4636) was detected
at roughly the same magnitude (I = 22.9 +/- 0.3).
Our results suggest that the source S1 is not a GRB afterglow.
