A. N. Morgan, B. E. Cobb, C. Klein, and J. S. Bloom (UC Berkeley) report:
We observed the field of GRB 090515 (Beardmore et al. 2009, GCN 9356)
with the 1.3-m PAIRITEL located at Mt Hopkins, Arizona. Observations
began at 2009-05-15 05:11 UT, 26 minutes after the Swift Trigger. We
detect no afterglow at the XRT position in a mosaic with an effective
exposure time of ~330 seconds.
The preliminary photometry (calibrated to 2MASS) yields:
post_burst
t_mid(min) exp(s) filt U. Limit (3 sig)
30 330 J > 18.0
30 330 H > 17.2
30 330 K > 15.1
All magnitudes are given in the Vega system. No correction for
Galactic extinction has been made to the above reported values.
