Delta Sco brightens mag V = 0.8

[Olivier GARDE]

Very small évolution for Del Sco since one year
Here's H alpha and H Beta profils taken with eShel spectrograph (corrected from Heliocentrique velocity)

Here is my recent (29Apr17) spectrum of Be star delta SCO:

Taken with the CDK17 reflector at F/6.8 and LISA spectroscope. The nearby F3V miles star HD150453 was used for IR correction (OBJCTRA= '16 42 11' / OBJCTDEC= '-19 51 08').
Numerous He lines appear and the spectrum shows the telluric O2 lines clearly on this low altitude object. Twenty 1-sec exposures were made to capture this very bright object!
