T. Minezaki (IoA, Tokyo), P.A. Price (IfA, Hawaii), Y. Yoshii (IoA,
Tokyo), L. Cowie (IfA, Hawaii) and Y. Kakazu (IfA, Hawaii) report:

We observed the localisation of GRB 080229 with the MAGNUM telescope +
MIP dual-beam imager. We do not find any afterglow in the RIYJHK images
within the XRT error circle (GCN #7343Loading...
 
 ). We estimated the upper limits
in JHK based on flux calibration with a nearby 2MASS star as follows:

  Filter   t - t_GRB (hour)    Limit (mag)
  J        +19.8               20.5
  H        +20.7               20.0
  K        +20.4               19.4
