Scientific paper

Spectroscopic observations of the long period variable epsilon Aurigae were made during its 1982-84 eclipse. It is found that the Ca II H and K lines show variation in their equivalent widths. The equivalent widths of these lines are larger before and after totality compared with that during totality. This phenomenon may be due to the atmospheric effect of the secondary.
