■ [Symbiotic Nova] Spectroscopy of V407 Cyg : update
We newly obtained the low-resolution spectrum of V407 Cyg at Jul. 18 UT. The spectrum shows the strong red continuum at longer than 8000 A. The red component is contributed from the red companion star in the system of V407 Cyg. It suggests that the photosphere almost shrinkage and the binary component come to be seen. The emissions of Pachen series and OI 8446 are not seen. The emission of H-alpha also weakened.
■ [Symbiotic Nova] Spectroscopic Observations of V407 Cyg : update
We newly obtained the spectrum of symbiotic nova V407 Cyg on May.11. The continuum became the redder comparing to the previous phase. The development of the redder region indicates that the radiation began to be affected from Mira-like secondary star.
