(GCN #806) with R=17.1 gives the following \nmeasurement for GRB000926:\n\nSept. 30.3075  R = 22.19 +/- 0.06\n\nAdded to the R-band data points used in the analysis by Hjorth et al.\n(GCN #814), to the previous CFHT observation and to the last data\nby Fynbo et al. (GCN #820), this new point confirms the change in decay\nrate announced in GCN #820.\nThe decay value is now 2.44 +/- 0.07, using data past Sept 29.2, while\nthe decay is 1.67 +/- 0.04 with data prior to Sept 29.2.\n\nA graph of the light curve in R with the linear fits can be found at\nhttp://www.cfht.hawaii.edu/~veillet/grb.html\n\nD. Kocevski, D. Donovan and G. Luppino are acknowledged for their \nhelp in this observation.\n\nThis message may be cited.\n\n-- \n************************************************************\nDr. Christian Veillet,       CFHT Senior Resident Astronomer\nPhone: (808) 885-3161   http://www.cfht.hawaii.edu/~veillet/\n************************************************************",
