Line profiles of faint 
lines of astrophysical interest are
observed in a conventional shock tube. Electron density is 
, and the temperature is 11 000 K. The Stark effect is the dominant
broadening mechanism. The line at λ 419.07 nm
(multiplet 7.26, Moore [CITE]) Stark width is
measured and compared with theoretical prediction.
