R magnitudes are given with their uncertainty.\nA photometric check on stars 1 and 2 leads to mg1 - mg2 = 0.658 +/- 0.01\nover the 6 nights of observations.\n\nA graph of the light curve in R from CFHT observations can be found at\nhttp://www.cfht.hawaii.edu/~veillet/grb.html\nas well as the last image of the OT vanishing in the background...\n\nWe are done at CFHT with the observations of the OT itself. The observing\ntime used for GRB000926 has been taken from allocated time to \ncolleagues from Canada and Hawaii who are once more acknowledged,\nwith for last night special thanks to M. Brodwin.\n\nThe field will be imaged again when CFH12K will be on the telescope for\na final photometric calibration before running the last analysis and \npublishing the data.\n\nThis run has been more hectic than the one on GRB000301C. Sorry for that... \nAloha!\n\nThis message may be cited.\n-- \n************************************************************\nDr. Christian Veillet,       CFHT Senior Resident Astronomer\nPhone: (808) 885-3161   http://www.cfht.hawaii.edu/~veillet/\n************************************************************",
