Do any members have spectra from the 2014 period which show the loss of emission lines????
EDIT: I should have said Lo-Res spectra. There are many Hi-res included in the Eta Car 2014.6 Campaign results.
There are some in this this forum, but none I can see which show a complete loss of the Ha.

I had 7 lo-res spectra of Eta Carinae from June-Aug 2014 but none showed disappearance of the Ha line, nor any significant change in brightness of the line for that matter.

Rob,
Thanks mate.
I'm now pretty sure the earlier report was incorrect.
