Wednesday 30 September 2009 by Francois Cochard

Observe the current Corot Be targets HD51193 & HD51452 (News)

Saturday 29 November 2008 by Francois Cochard

In the current Corot run (started early November and up to March 2009), there are two Be stars acessible to our instruments : HD51193 and HD51452. This is important to get simultaneously spectra form these two stars, to compare photometry and spectrometry evolutions. Please observe these star in priority, and inform immediately the community if you detect any evolution in the spectra !

I just modified the expected observation period for these two stars : it is now changed to 10 days (365 before).

Go to your telescopes ! (:>)
