- Аннотация: We present the results of our spectroscopic observations for the classical symbiotic star V1413 Aql in 2012-2017. In this period the system was in both active and rare (for it) quiescent states. In 2012 the optical spectrum was dominated by the radiation from the erupted hot component of spectral type F47 III. In 2017 the system passed to a quiescent state that lasted at least three months. In this period lines of ions with high ionization potentials, such as He II 4686 Å and CIV 5802 Å, appeared in the spectrum. The temperature and luminosity of the hot component in this period were K and . We show that the quiescent state in 2017 differs little in its time and energy characteristics from the previous active state observed in 1993.
