2D spectrum by P.Dubreuil, slitless grism spectrograph
main-sequence stars).
The system is a binary composed of a Herbig Be star and an FU Ori star. The Herbig star is
embedded in nebulosity.Coordinates (2000.0) : R.A. = 07h03m43.2s, Decl. = -11°33'06"
This double pre-main sequence star is now relatively brigth, around mV 8, and well placed in the northern sky. It would be interesting to cover the outburst on the whole visual and IR spectrum at low and high resolution as both components of the system have their own spectral contribution.

Conditions for use of data in
publications
Note
there is no validation check prior to adding spectra to this table.
Users should verify the quality of the spectra with the observers
concerned.
Use of these data in research publications is encouraged subject to the
following conditions: The observers concerned should be contacted
to confirm the particular acquisition and data reduction procedures
used.
