Robin Leadbeater has been monitoring the long period binary variable Eps Aur with his LHIRES spectroscope and has observed a redshift which indicates the start of the eclipse. The last such event was back in 982.

Well done Robin!!!

Thanks Rich  :D,

What has been happening to the KI 7699 line since is pretty interesting so I wrote it up in a poster paper for the Leeds BAA meeting earlier this month.
