We present new infrared observations of the exotic X-ray binary system Cygnus X-3, including high-time-resolution simultaneous H- and K-band photometry over ∼1.5 orbital periods and 1–5 µm photometry during both periods of apparent infrared quiescence and flaring activity. The simultaneous H- and K-band observations reveal the 4.8-h orbital modulation of the source, superimposed upon which are a n...
