The optical transient is detected \nat R = 21.2 +- 0.2 (preliminary calibration, partly based on zero points\nfrom previous nights, partly on USNO-B1.0 reference stars). The resulting\ndecay rate is quite slow, with an average power-law decay index of ~ -0.9\nsince the detection 7 hours after the burst (Monard GCN #2324).\"",
