John Observatory of University of\nCanterbury) reports on behalf of the AAVSO International High Energy\nnetwork:\n\n Two sets of frames centered on the coordinates for GRB040916 (Yamamoto et\nal., GCN 2712;  HETE trigger 3558) show a stationary object not visible on\nDSS2 R and IR images, at:\n\n          RA = 23 01 44.01 Dec = -05 39 11.3 (2000.0) \n\n Unfiltered R magnitudes at mean times\n         08:29 UT  19.7  S/N = 2.8\n         09:54 UT  19.9  S/N = 3.3\n\n Observations were made under clear conditions with the 0.6 meter\ncassegrain telescope with f/6.4 focal reducer on Mt. John. Seeing was\napproximate 3 arcsec and limiting magnitude roughly 20.5 in R. The USNO\nA2.0 catalog in Astrometrica was used for photometry and astrometry\nreduction. CCD field of view was 9x9 arc minutes.\n\n More information on the exposure and the FITS image itself is available\nat:                ftp://ftp.aavso.org/grb/\n\n Note, there are many red sources in the field and these observations are\nunfiltered so there is a strong possibility that this OT candidate is just\na faint red source.\n\n  The AAVSO International High Energy network is greatful for a generous\ngrant from the Curry Foundation and to NASA for the financial support for\nthe High Energy Workshops for Amateur Astronomers and to the SWIFT E/PO\nprogram for continued funding.",
