Following the detection and subsequent monitoring by SWIFT and MAXI of
1RXS J043657.1-161258 (GCN#16981, ATEL#6654, GCN#17016) we took
spectroscopic data of its likely optical counterpart. The observations
were conducted with the 0.6m TELMA robotic telescope at the
BOOTES-2 (+COLORES) astronomical station in Malaga (Spain). The optical
4000-9000A spectra were acquired at Oct 4.95686 -- 5.07087 UT.
The spectra contain broad molecular TiO, CaI, MgI, NaI lines plus a red
continuum. We also detect Halpha and Hbeta in emission. These spectral
features are indicative of a still active red-dwarf flaring star. Further
optical observations are on-going.
