Descripción
It was recently reported that the black hole candidate X-ray binary MAXI J1659-152 has faded to an X-ray flux (0.5-10 keV) of < 3.0e-13 ergs cm-2 s-1 (ATel #3506). This implies the source may be in quiescence after an outburst that lasted almost one year (GCN #11296, ATel #2873) including a late re-brightening in the last three months (ATels #3298, #3339, #3358, #3379). Here we report on recent optical observations with the two 2-m Faulkes Telescopes North and South (see ATel #2884).
