|2003 NZ6 was observed for just 11 days from 2003 July 9th - 20th.
It spends a lot of its time close to the Sun and the NEODys database
indicates that the next favourable apparition is likely to be May 2005
when it should reach about mag. +19.
At this time the 3 sigma uncertainty in the ephemeris position is
about +/- 1° and it may well be possible to recover it at that time.
Strangely NEODys gives the uncertainty in position at the next
favourable apparition after that, in June 2010 as much smaller at +/- 2'
and slightly brighter at mag +18.5.
In July 2015 there is the chance of a very similar apparition to
2003, with a close approach to 0.088 AU predicted for 2015 July 18.8.
