I'll have to look it up, but there is one near the Dumbbell Nebula that we should be able to detect. The latest Sky & Telescope magazine carries an article about the Kepler spacecraft and its serach for traniting planets. Worth a look-see!

I really didn't follow all the technical issues you brought out in your analysis, but I got the gist of what you were doing. Besides all the planning for this, you were very persistent and patient throughout the entire process, and I'm so glad you had optimum viewing conditions as a reward for all your preparations. I am looking forward to your upcoming talk on Feb 13th about more of how you did it all. Many, many kudos to you! Randy,

Sorry for the delayed reply. The planet is going around the star on the left, which is the slightly brighter member of the pair. This was the ideal situation to observe because the right hand star was used as the reference star (it is known to not vary with time and is of the same type-sequence as the measurement object). By definition, the reference star was "constant" at a magnitude 9.1. On Feb 13th I will talk more about the "noise" in the measurements and how statistical analysis is useful in the analysis to this level of accuracy. Clear Skies! Hello all!

It is amazing to realize that you can detect a planet crossing in front of a star 190 light years away!! The change in brightness matched your prediction -- even though the change is so small, the light curve clearly shows it. Second, are you able to plot the light curve of the other star as a reference? I don't know how difficult that would be, though. Lastly, which star is has the planet -- right or left in the image? Well Done! Tim Randy,
