Scientific paper

We report observations of the G0 subgiant eta Boo made in 1998, in
Balmer-line equivalent width with the 2.5-m Nordic Optical Telescope and in
velocity with the 24-inch Lick CAT. In both data sets we see an excess in the
power spectrum, with oscillation frequencies that confirm the earlier
observations by Kjeldsen et al. (1995).
