Description
Observations of the black hole binary XTE J1859+226 revealed an
unexpected optical re-brightening. Images were taken with the Nordic
Optical Telescope (NOT) using ALFOSC on Jul 13-14, the William Herschel
Telescope (WHT) with ACAM on Aug 8 and the Isaac Newton Telescope (INT)
with WFC on Aug 19 at the Observatorio del Roque de los Muchachos, La
Palma, Spain. The target is found ~1 magnitude brighter than its
quiescence level of R=22.48 +- 0.07 as reported in Zurita et al.
