Re: Dramatic change of H alpha profile

Interesting as we have been observing the same target last night - a good way to compare our results... and lot of work for the ARAS database administrator François Teyssier!... specially as we have time series (and time seems very critical on CH Cygni with changes within minutes!) and for the eShel spectrograph data we have a large spectral domain with multiple orders... not easy to handle. Have a thought for him! 
Looking forward for the OHP spectroscopy workshop where people there will certainly talk about CH Cygni and those changes!...
