A high resolution spectrum (R=15000) taken tonight shows H alpha to be in emission

There are a number of publicly available archived high resolution spectra taken with the ELODIE spectrograph at Observatoire Haute Provence between 1998 and 2005. None of these show H alpha in emission so this may be unique to this dimming.

Plots of the ELODIE spectra and comparisons with my spectra at both low and high resolution can be seen here on my website

Is there any professional interest in these observations ? If so who should I be talking to for guidance on what specifically I should be focussing on (resolution, specific regions/lines)
