    I was wondering IF (or how?) I could find Comet ISON on Stellarium?
    (I have 0.12.4)
    Do I have to download anything to be able to find comets or what?

    Add this data to the ssystem.ini file and then search for by the name c/2012 S1

    [C2012S1(ISON)]
    parent = Sun
    orbit_Inclination = 62.3976
    coord_func = comet_orbit
    orbit_eccentricity = 1.000003
    orbit_ArgOfPericenter = 345.5647
    absolute_magnitude = 7.5
    name = C/2012 S1 (ISON)
    slope_parameter = 8.0
    lighting = false
    tex_map = nomap.png
    Color = 1.0, 1.0, 1.0
    orbit_AscendingNode = 295.6529
    albedo = 1
    radius = 100
    orbit_PericenterDistance = 0.012443
    type = comet
    orbit_TimeAtPericenter = 2456625.7741

      stellarium 0.11.4 on vista 32bit

      i had to remove the '/' character within the []s and change "Parent" to
      "parent"... my original entry was working but the new one did not when
      pasted in ssystem.ini as posted... i adjusted the name field to temporarily
      be different so i could visually see when both entries were found in the
      find box... just thought you might like to know...

      question: my original entry shows this comet to be near mars when viewed
      from my location... the new entry shows this comet to be at the sun...
      changing "ArgOfPericenter" to "orbit_ArgOfPericenter" as my original entry
      has doesn't make any difference... which one (entry) is correct?

    Comet C/2012 S1 ISON is already included in the ssystem.ini file that comes with version 0.12.4 You will find it as C/2012 S1 ISON in the search panel.

    There were three syntax errors in the updated coords I gave for C/2012 S1 due to an error in my generation program. This is the corrected version. Orbital elements date 3/10/2013 from MPC

    [C2012S1(ISON)]
    parent = Sun
    name = C/2012 S1 (ISON)
    lighting = false
    tex_map = nomap.png
    Color = 1.0, 1.0, 1.0
    albedo = 1
    radius = 100
    coord_func = comet_orbit
    orbit_Inclination = 62.3976
    orbit_Eccentricity = 1.000003
    orbit_ArgOfPericenter = 345.5647
    orbit_PericenterDistance = 0.012443
    orbit_TimeAtPericenter = 2456625.7741
    orbit_AscendingNode = 295.6529
    absolute_magnitude = 7.5
    slope_parameter = 8.0
    type = comet

    Add these parameters to the ssystem.ini in place of the old version if necessary

      I'm using Stellarium 12.2 and stellariumscope to control my mount. The reason I haven't updated to 12.4 is because I'm not sure that the current version of stellariumscope will work with 12.4 If I paste the above parameters to my ssystem.ini will ISON show up in the search? Or, does the current version of stellariumscope work with 12.4?

        OK this is weird. As I said I'm using 12.2 and without changing the ssystem.ini ISON is already in there. I thought ISON was just included in 12.4. So I'm just glad that I can find the comet now.

    Peoples, why you do not use Solar System Editor plugin for adding/updates comets/asteroids?

    I have 12.4 and I see the information in the ssystem.ini file, but when I search for it, all I get is c/2006 P1 (McNaught)

    hello Barry,

    i have an equal Problem.
    I have 12.4 und see the information in the ssystem.ini file. but when i search for the entries, it seams like everything after the Entry [136108haumea] could not be found.

    I have Stellarium on Win 7 and I have a separate ssystem.ini file in my user area. I just inhibited it and used the distributed ssystem.ini and I agree the details are there under C/2012 S1 but it is not found as you say. I think there is a problem with ssystem.ini file that is distributed with version of stellarium you have. I just copied the latest version of the ssystem.ini file to the stellarium folder and it works correctly. Try this

    I have examined the ssystem.ini file distributed with Stellarium and this:
    [c2011l4%28panstarrs%29]
    type of entry I suspect is the problem. The "%" character is not recognised just like the "/" in the title and the file stops reading

    I downloaded 12.4 for OSX (10.9) and at first I couldn't find ISON either. However, the problem was that the config settings from my old install of stellarium were being used. So the old ssystem.ini was still there... Look in your local "~/Library/Application Support" directory. To start fresh, just delete/trash the Stellarium folder you find there. Then re-open Stellarium and it will make a local copy of the new data (found at the system level in "/Applications/Stellarium.app/Contents/Resources"). Voila!

    In Windows7 delete the directory
    C:\Users...\AppData\Roaming\Stellarium

      Or just change the ssystem file there. It worked for me.

    I have the latest version of Stellarium and i can find ISON, but its position relative to the Sun does not change if i go forward in time. How can i see its movement in time lapse?

      same problem. I copied in the coords information (from Barry 2013-10-03 post... see above) into the ssystem.ini file with notepad, replacing what was there, and now it works fine.

    Yep, changed ssystem.ini within roaming folder in W7-64bit and it finds it, but I do not see it!

    Now that ISON has survived the trip around of the sun, I decided to "refresh" the orbital information using the standard plug-in update procedure (in 0.12.4) just in case there was a course correction.

    BIG MISTAKE !!! ISON now tracks as the sun.

    Please help.

    Why is comet Ison showing right next to the Sun if it'll be closest to Earth on Dec 28th on its way toward (direction of) Polaris? Does anyone know and can provide the coordinates of Ison as of Dec 18th 2013? Thanks

    According to my stellarium 0.12.4 Ison is about .47 au away and heading in our direction at a few miles/sec.

      ummm... ISON is gone, isn't it? broken up on the way around the sun and nothing
      more than debris at this time? that's what i read on all the monitoring sites :?
