You can look at BeSS database. There are currently 167 spectra around
H-alpha that you can browse using ARASBeAm front-end:
Otherwise, go directly to BeSS database : http://basebe.obspm.fr/
There are 430 spectra of del Sco taken by about 16 different amateurs
and some professionals. You can look for a certain time range and
download the spectrum.
BeSS database will be presented a week from a IAU Symposium 272: "Active
OB stars: structure, evolution, mass loss, and critical limits"
(http://iaus272.obspm.fr). ARASBeAm will have a poster - this is a
front-end for amateur spectroscopists to help them identifying which Be
star target to look for.
In parallel, some discussion & talks are scheduled around del Sco at
this symposium... it already looks promising!
Address: Les Roussets, 38420 Revel, France
...vous ne verrez plus les étoiles comme avant !
