Kubanek (FZU AV CR\nPrague), report on behalf of a large collaboration:\n\nWe imaged the field of GRB 120327A detected by SWIFT (trigger 518731)\nwith the Watcher robotic telescope (D=40cm) located at Boyden\nObservatory, Bloemfontein, South Africa.\n\nOur first good observation was 14.4 min after the GRB trigger, 3 min\nafter receipt of the GCN notice. The source was close to the zenith\nwith an airmass of 1.01. \n\nWe detect a fading source in the error box given by SWIFT, which\ncoincides with candidate counterpart mentioned by Sbarufatti et al.\n(GCN 13123).\n\nThe optical transient was measured at 15.5 +/- 0.1 mag @ 14.4 minutes\nafter the trigger in the clear filter.  \n\nMagnitudes were estimated using the nearby USNO-B1 stars as references\nand are not corrected for galactic dust extinction.\n\nAnalysis of the remaining images is on-going.",
