I have a problem with the position of asteroids in CdC V2.75.
When I select the Asteroid and refresh it in Select Catalogue & Display
Conditions I get a warning that the Orbital Elements are one year older than
the actual date.
However I have downloaded the new elements a few minutes ago.
Is there something wrong with the elements, my setup or am I doing
something wrong ?
Also and this may be related now that Pluto has two existences in CdC both
as a planet and as Asteroid 134340 I have searched for the position of both.
They give completely different results !
As follows:
Planet
Pluto 2006- 9-24 21h04m
Magnitude: 13.9
Diameter: 0.1 "

Asteroid
134340 Pluto 2006- 9-24 21h05m
Magnitude: 25.1
Phase: 1 °
Distance: 41.0986 au
Solar Distance: 42.0042 au
Solar Elongation: 154°
J2000 RA: 23h05m21.30s DE:-20°30'46.6"
Date RA: 23h05m42.79s DE:-20°28'35.4"
Home - Carshalton 2006-9-24 21h05m ( TU + 1h00m )
Sideral Time : 20h18m
Hour Angle : 21h13m
Azimuth :+140°42'
Altitude :+09°27'
Rise : 19h43m Azimuth:+123°13'
Culmination : 23h56m
Set : 4h09m Azimuth:+236°47'
Distance to the last object : +00°00'00.0" PA:180
Both details by searching for the object and then using the identification
feature and copying the text to the clip board - I am not sure which (if
either !) is correct.
This may be related to the problem with the asteroid information above but
the fact that Pluto is included as an Asteroid indicates that the elements
are not one year old since the number for Pluto was only given earlier in
September 2006.
