> Hello Everyone,
> 
> I'd like to remind observers about the upcoming GL 581 b transit window
> which is centered on April 2, 15:46 UT. (See the transitsearch list
> archive for the original campaign e-mail):

> 
> The April 2 opportunity is well-suited to Australian and Japanese
> observers, but transitsearch participants worldwide are _urged_ to
> observe. The probability of a transit is 3.6%, and the scientific value
> of a detection would be enormous (the first transiting Neptune-mass
> planet). A central transit should have about a 1.5 hour duration. If
> our models of this planet and red dwarf star are correct, the transit
> depth should be about 1.7%. It doesn't get much better than this.
> 
> See www.oklo.org for recent posts on this system, and for other
> exoplanet-related news.
> 
> with best regards,
> Greg
