Hello,
I've been proactive here a bit, did observe this star since April but seen no emission in the 6700-7000A range (have quite a few non-detections, not including here).
Comparing to Paolo's profile, the Ha-absorption must have changed a bit (R~2600):

And made a hires (R~17000) attempt earlier:

The H-alpha peaks have varied somewhat (~15%) during these 3 x 1800 sec attempts.
Sent the fits to database.
However, for high resolution I'd guess the OH telluric regions and the LI 6707 was mentioned, and that highest resolution required to detect emission. Again, do have a few negative observations, question if needed in the database at all. If not, first I'd do noisy probes (3-4 minutes) and give high exposures when seeing anything.

EDIT: the R~2600 was shot on MAY-13, mistake in the image title. Fits sent are correct.
