  "body": "The optical counterpart of GRB010222 has been observed using the \nCFHT Multi Object Spectrograph in imaging mode at the Cassegrain \nfocus of the 3.6-m CFH Telescope on the night of March 1 to 2. \n\nTwo 10 mn images were obtained with a seeing of about 0.8\". \nPhotometric reduction made as outlined on GCN #1000 leads to: \n\nMar. 2.641   R = 23.10 +/- 0.10 \n\nThe index of the power law decay fitting the R light curve data \nsince 0.6 days after the burst (including the revised and new \nmeasurements by Holland et al. in GCN #1002) is 1.25 +/- 0.03, \nthe same as our previous determination (Veillet, GCN #1000) and \nnot significantly different from the GCN #1002 value. \n\nWhile a few objects are now seen in a radius of 4\", the OT is \nstill a point like object. \n\nMore information (with the new images of the OT) can be found at \nhttp://www.cfht.hawaii.edu/~veillet/grb.html \n\nM. Pakull, L. Mirioni, and J. McDonald 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************************************************************",
