report on behalf of EAFON team:

"We have imaged the GRB 060515 field (Cummings et al., GCN 5132) with
J and Ks band using CFHT/WIRCam. The observation started from 3.18
hours after the trigger.  There is no new sources in the XRT error
circle (Page et al, GCN 5139) to a limiting magnitude of J > 20.0 and
Ks > 18.9 derived from several 2MASS objects in the fields. The
possible TAROT afterglow (Klotz, Boer, and Atteia, GCN 5134) do not
appear in our J and Ks band images to the same limiting magnitude.

Time(mid) Exp      Filter Limit (SN=3)
----------------------------------------
3.23 h    20s x 7  Ks     >18.9
3.34 h    20s x 7  J      >20.0

We thank Dr. Cabanac, Dr. Loic, Dr. Wang and the staff of QSO team."
