A coordinated spectral observation with Olivier on VY Scl by using a modest 8-inch Nexton telescope and a Star'Ex spectrograph (3D-printing). From France at the elevation of 14° only above horizon. See the result on the link given by Olivier.
Also, you can find spectra of V794 All and V704 And.

Alert Notice 841 requests coverage of VY Scl in support of HST Target of Opportunity observations scheduled for November 17 UT. Please see the notice for details and observing instructions. Please note that because of VY Scl's current faintness (V mag ~18), spectroscopy is not requested at this time.
