Observations of CYG X-3 in the I band.
Abstract
Cygnus X-3 has been detected in the I-band in four CCD images taken on the Multiple Mirror Telescope. The magnitude is within 0.2 of 17.0 and there is evidence for variability over the two months of observation. The column density of intervening hydrogen is in agreement with that deduced from the X-ray spectrum.
