136199 Eris - Dwarf Planet (2003 UB313)

Dwarf Planet (136199) Eris   
Observation of Eris on 2009-09-20, lying in starfield in Cetus

Faint object marked by cross-hairs lies at the forecast position of Eris on 2009-09-20 
has approximately the correct magnitude (+18.3 measured vs. +18.7 predicted)
and is not present on a DSS Reference Image, or on image taken 18 days later.

Eris is the largest known object in the Kuiper Belt with estimated diameter of 2,500 km
(it was previously known at 2003 UB313)
The bright star in the image is HIP 7802 (mag  +8.8)

There are two nearby very faint objects but these are
sufficiently far away and are just about recognised in my

Note : absence of any object the position of the later suspected object.
Image
Expected position of Eris on 2009-09-18 is indicated by the black circle.
 
With predicted magnitude of 18.7, Eris is probably too faint 
to seen in this image (mag limit +18), and in any case would also
almost certainly be lost in the glare from the adjacent mag +8.8 star.
Note : the absence of any star object at the position of suspected object 
two days later.  However this is not definitive evidence since the magnitude limit of 
the image is not quite sufficiently deep. It can be seen that there 
are a number of other objects (star/faint galaxies) which can be seen in 
the  2009-09-20 image but not in the earlier 2009-09-18 image.
