Abstract:
We present the results of optical spectral and photometric
observations of the nucleus of Markarian 6 made with the 2.6-m Shajn
telescope at the Crimean Astrophysical Observatory. The continuum and
emission Balmer-line intensities varied by more than a factor of two
during 1992-2008. The lag between the continuum and Hβ
emission-line flux variations is 21.1±1.9days. For the Hα line
the lag is about 27-days, but its uncertainty is much larger.
Description:
The Hα and Hβ spectra of the Seyfert galaxy Mrk 6 were
obtained from the CrAO 2.6-m Shajn telescope.
