Description
In response to the detection of the X-ray source Swift J0732.5-1331 (ATEL #697, #735, #757, #760), we observed its optical counterpart with the Mt. Hopkins 1.5m telescope equipped with the FAST spectrograph. A total of 22 spectra covering 3480-7410 A were acquired between Jan 22 and Mar 1. A 3" slit provided 6 A FWHM resolution. In addition, on March 5 we acquired 2.3 hours of spectroscopy (14 spectra) with the 600 gpm grating and a 2 arcsec slit width (4490-4895 A; 2.4 A FWHM).
