A day before, Stephane Charbonnel had made first a spectrum of this object and the 27th, we redid some spectra time serie of this objet at OHP, with three observers : Stéphane Charbonnel, James Edlin and me.

The evolution of H Alpha line was very fast, we saw the evolution each 10 minutes.H beta also moved but less significantly.
Each spectrum is a 10 minutes exposure and we followed this target overnight. All spectra taken with a LISA.
Here's the Atel telegram with the comment of Dr. Steve Shore.

A great thank you to Dr. Steve Shore who has followed all our observations during the OHP workshop and analyzed our spectra.
This is a real time spectroscopy.....
