RA 13h47m38.21s Dec. +02°14'33.9"
60-minute exposure
Size = 150" x 150"
Siding Spring Observatory-DSS plate S864-02OA
A single additional image from DSS in 1984 slightly refines the orbit of this TNO.
The following astrometry was submitted to the Minor Planet Center:
K07J43H 1984 03 07.72942 13 47 38.21 +02 14 33.9 260
At the end of this page are the elements and residuals before and with the new data. The new orbit is more accurate because the object
has now been observed for 24 years instead of 14 years. 2007 JH43 was numbered on 2016-07-19.
