I continue the survey tonight, and re discovered the emission of this star.
Spectrum look similar.
Francois (LISA) & Christian (VHIRES), can you send me your spectrum ? I will update the ARAS web page with these spectrum.

Also for me, two observations of HD189847 in HR mode (R=50000). One hour exposure VHIRES + C11. No significant change for the two dates.
