A list of sky lines that can be found in spectra (read … handy sky lines!):
wavelength (in Å):
5577.3 ( > 5579)
5893 ( > 5890, 5896)
6300.3
6363.8 (1/3 of 6300.3)
An excellent and very convenient tool to find and plot the sky lines from 3140 – 10430 can be found at vizier, catalogue J/A+A/407/1157 (Hanuschik+, 2003)
UPDATE 17/11/2015: Another good list of lines is given by the ESO/UVES team in their UVES sky emission spectrum.
A small (but growing) list of selected (read handy!) optical lines:
