Hi all, Ha Ew, taken between 6559A and 6567A seems to climb at an increasing rate as the R emission part disappeared from the spectrum. First part of the EW ...
Some comments and questions I think we should tread carefully here regarding contact points. Contact points have been determined in the past via photometry. I ...
All - I thought you would like read this at below. I got this from my friend of mine Joe Rao, our New York meteorologist. Frank J Melillo Just received this...
Last spectra from eps aur, SNR122, min wavelenght 6496.544, max wavelenght 6609.054, exp 2400s. R=15500 on 6532.8 neon line. Corrected by instrumental response...
All - I did some Eps Aur photometry on April 1-2, 2010 and I came up with an average +3.74 V magnitude. I think the brightness is holding it off. Jeff - I...
Attached is the latest update of the intensity changes in this line. It looks like we have hit the peak and are on the way down, as was also seen by Lambert...
The list has been updated and now includes links to the spectra appearing in past newsletters. http://www.threehillsobservatory.co.uk/epsaur_spectra.htm The...
All - I did some Eps Aur photometry on the night of March 6 - 7, 2010 and I came up with an average +3.76 V magnitude. Jeff - I will send you the data report....
Poor weather has put another 8 day gap in my 7699A neutral potassium line data but measurements through thin cloud last night suggest that the absorption line...
A bit of topic, but here is my "Epsilon Aur Observatory" http://www.fredda-o-ac.se/KPO/equ.htm Snow one more day and i is lose for ever. Regards H.G.Lindberg...
All - I did some Eps Aur photometry on February 20th at 5:00 UT. Surprisingly, I came up with an average +3.77 V magnitude. So, it got fainter again since...

All - I did some Eps Aur photometry on January 28th at 0:20 UT. I came up with an average +3.70 V magnitude. It did get fainter a bit since late December. So...
The latest update on the regions of the spectrum I am tracking using high resolution spectroscopy (KI 7699, H alpha, H gamma) is now on my website. ...
I got a new mesaurment of eps Aur this evening. The sky was quite hazy and there was a greater spreding between the measurments than usally. My result was...
Hi all, Recent echelle spectra: http://astrosurf.com/buil/star/epsaur/epsaur.htm (note 6-month violet to red ratio evolution of Halpha line). Also dynamic...
