Hi All,

Based on observations from Chile on November 6th of the occultation of
an unnamed star by the dwarf planet Eris, it appears that the crown for
the 9th largest body in our Solar System may have to be returned to
Pluto. Data is still being reduced and numbers crunched, but it appears
that the error bars to the positive side on Eris' size would still make
it smaller than the smallest estimate of Pluto's size. Alain's initial
personal account can be read here:

A detailed story by Kelly Beatty is now up on the Sky & Telescope
website:
