Abstract: This contribution reports on the detection of Doppler-shift oscillations in an active region observed on 2007 August 22–23. The oscillations, which have a much lower amplitude than those observed with earlier instruments, have periods of 7 to 10 min. These observations include density-sensitive emission lines and oscillations are also present in the derived densities. EIS is capable of detecting coronal velocity fluctuations with amplitudes of less than 0.5 km s-1 with short integration times in strong coronal lines, potentially allowing access to a much richer range of coronal oscillatory phenomena than has been available with earlier instruments.
