Resumen:
We present the results of prompt optical follow-up of the electromagnetic counterpart of the gravitational-wave event GW170817 by the Transient Optical Robotic Observatory of the South Collaboration. We detected highly significant dimming in the light curves of the counterpart ({{∆ }}g=0.17+/- 0.03 mag, {{∆ }}r=0.14+/- 0.02 mag, {{∆ }}I=0.10+/- 0.03 mag) over the course of only 80 minutes of observations obtained ̃35 hr after the trigger with the T80-South telescope. A second epoch of observations, obtained ̃59 hr after the event with the EABA 1.5 m telescope, confirms the fast fading nature of the transient. The observed colors of the counterpart suggest that this event was a ?blue kilonova? relatively free of lanthanides.
