The  \nsource is exceedingly bright in the first few minutes, visible on  \nindividual 7.8 sec exposures in JHKs bands. Preliminary photometry,  \nwhich may be affected to non-linearities at these bright flux levels,  \nis given below.\n\n# t (MJD)       terr (day)      filt     mag     merr\n#####################################\n\n54544.262141    0.000454        k       8.613900         \n0.033214        0       0\n54544.261788    0.000454        j       9.110600         \n0.041347        0       0\n\nA comparison with 2MASS may be found at:\n    http://lyra.berkeley.edu/~jbloom/grb080319b.png\n\nThis message may be cited.",
