(GCNC 3913) source candidate in the first\nanalyzis reported in GCNC 3911. This source is\ndetected in three composited images taken by TAROT\nin the 8 first minutes after GRB. Magnitudes are\ncalculated using the R USNO-B magnitudes of three\nnearby stars.\n\n[sec after GRB]\nstart      end    magnitude\n    86      144    R>18.1 +/- 0.3 (no detected)\n   150      253    R=18.5 +/- 0.3\n   312      370    R=18.7 +/- 0.3\n   376      479    R=19.1 +/- 0.4\n\nCorresponding images can be seen at:\nhttp://www.cesr.fr/~klotz/grb050904\n\nAfter 8 minutes, the CCD camera cooler failed.\nThen, images are very noisy.
