Optical photometry and Halpha Spectroscopy of SWIFT J1910.2-0546/MAXI J1910-057
Abstract
We report on optical photometry and spectroscopy of the black hole X-ray transient Swift J1910.2-0546/MAXI J1910-057 (Krimm at al. ATel #4139, Usui et al. ATel #4140). R-band photometry (time resolution 27s) over an interval of 3.1 hr was obtained using ALFOSC on the 2.5m Nordic Optical Telescope (NOT) on the night of 21 July 2012. The light curve is dominated by flickering superimposed on a smooth, approximately sinusoidal variability of amplitude ~0.02 mags and ~4 hr time scale.
