Question: what is the best discovery you have made

Guy Rixon answered on 2 Mar 2018:

I found a special kind of eclipsing binary-star. The Gaia telescope saw its outburst and I was the observer who first observed from the ground so that the team could work out what it was. It’s a rare kind of star-system and the only known one of its kind that is edge on so we can observe the eclipses.
