Descripción
We report on high resolution Halpha spectroscopy and time-resolved
photometry of the optical counterpart to the X-ray transient Swift
J1357.2-0933 in outburst (Krimm et al. ATEL #3138). SPECTROSCOPY: Six
30-33 min spectra were obtained on the nights of 2011 Feb 25-27 using
the IDS Spectrograph on the 2.5m Isaac Newton Telescope (INT) at the
Observatorio del Roque de Los Muchachos. The observations were performed
with the H1800V grating and a slit width 1.6 arcsec to yield a spectral
coverage of 6270-7000 Angs with a 30 km/s FWHM spectral resolution at
Halpha..
