Thanks Robin, sure i keep going observation on LhiresIII. Is the return of the red Ha wing can be consider as a spectroscopy beginning og the third contact,...
Hi Thierry, I think the disappearing and reappearing emission wings are part of the eclipse as it also happened in past eclipses. See fig 2 in this paper for...
Also this description from the 1956 eclipse which seems to agree with what we are seeing http://cdsads.u-strasbg.fr/cgi-bin/nph-bib_query?1957PASP...69..402W ...

No models, lot of mysteries, that sounds good for observers at least. New spectra, a little bit hazy, from this evening. Still there. Amitiés T 2010/12/2...

All - I did some Eps Aur photometry during the night of December 7-8, 2010 and I came up with an average +3.70 V magnitude. It is certainly a bit brighter now...

I have got the same trend in my data, that epsilon is brightening again. The star is a bit late compared to the previos 63 day period. My latest photometric...
The Stefanik et al paper is particularly interesting as they publish the residuals to the fit, ie the variations in radial velocity which are not due to the...

Thomas - Yes, I would say the same thing that the 60 day period is a bit late. Or perhaps the OOE period is about 65-70 days. I think it varies. Really,...
Last night was the first clear night in several days. Epsilon Aurigae continues to brighten, most significantly in the shorter wavelengths. 07/08 December 2010...
Greetings All, Pavel Chadima will be publishing an analysis of some HVAR photometry which will discuss the recent periods of the OOE. You all are in the right...
Hi Thierry, I just checked back and Pavel Chama contacted me and Jeff also in September but he then decided he did not need our data. I suggested trying my...
He contacted me in the same way . Finally my spectra doesn't match well with their, the resolution were two high compare to their own and prefer to use lower...

Hello Jeff I always wondered why the Rj vs. Rc, Ij vs. Ic, and even R vs. I band measurements of eps Aur seem to be mixed up so often This is IMO due to...
