摘要
We present the results of our UBVJHKLM photometric and spectroscopic observations of V407 Cyg obtained in 2003-2015. No fast brightness variations of V407 Cyg have been detected since its RS Oph-type outburst in 2010. Now the binary demonstrates a low-excitation emission spectrum with Ha weaker than the [N II] 6584 angstrom line. It is a typical spectrum on the way to the passive state.
