Exoplanets in STEREO Update

Glenn White of the Rutherford Appleton Laboratory, who is seriously hunting exoplanets with the STEREO SECCHI instruments, kindly provided a link to the HD2638 light curve they generated. No detectable transits. It turns out that the usable limit for exoplanet detection is around magnitude 8, and it's a lot harder than I thought (and I thought it would be pretty hard at that).

Still, it is possible, people are working on it and STEREO turns out to be an even more amazing instrument.
