GW 170817(apparent)

¡ TAROT is a rapid, h igh throughput instrument§ Focussed on the beginning of the EM transient§ Able to explore wide areas

¡ TAROT is more ef f ic ient i f posi t ions, and update of , are t ransmitted ASAP§ We are currently designing tools for a more efficient automatic early pointing§ And repointing when the position is updated or information comes in (e.g. GW170817)

¡ No threshold problem for TAROT§ It is designed for automated exploration of the transient sky

¡ Other ongoing programs§ Swift§ Neutrinos (TATOO - ANTARES)§ Fermi-GBM (subthreshold)§ Remote Space Objects with CNES§ Chilean program on variable stars§ Soon SVOM
