Abstract

A search of rapid and slow spectral variations of Balmer lines with time resolution from seconds, minutes, months, and years is carried out for 48 Per. In total, 40 spectral scans in the Hα and 13 spectral scans in the λλ3500-5300 Å region were secured during 6 nights. The results of this study show that, in general, there are rapid variations of Hα at the limit of the noise level. Large changes with time scales of months and years in Hα and higher Balmer lines have been investigated for the first time in 48 Per.
