Hello Mineo,
I think there is not possible to produce Sun TLEs, at least that I know.
On http://amsat.org.ar/pass.htm, Sun position is calculated.
I attach sunpos.js where you have a function to calculate Sun lat/lon.

If you load on your web sunpos.js (attached) and include in a web page
<script src="sunpos.js" type="text/javascript"></script>
Calling this sunpos function will return Sun's latitude longitude.
Hope this is of any help, nevertheless please advice if I can be of help.

Thanks for the attqached 'sunpos.js'.

<HTML>
<HEAD></HEAD>
<BODY BGCOLOR="#FFFFFF">
  <script src="sunpos.js" type="text/javascript"></script>
</BODY>

But, Nothing changes on my browser by the above description.

By the way, I found MOON TLE on your web.

MOON
1 00000U 00000    16179.56434792  .00000000  00000-0  10000-3 0 00001
2 00000 018.4553 004.0484 0463000 029.4136 333.1953 00.03660099000006

This MOON TLE is nice.

I previously found SUN TLE on a japanese official site.
Previously it was well tracking, but it is now overflows.
(Already it solved correctly.)

SUN
1 00001U 00  0  0 95080.09236111  .00000000  00000-0  00000-0 0  0017
2 00001 023.4400 000.0000 0000000 282.8700 075.2803 00.00273790930019

Hello Mineo,
Here is a working html example using sunpos.js at your site:

------------------------------------------------------------------------------------
<HTML><HEAD></HEAD>
<BODY BGCOLOR="#FFFFFF">
  <script src="sunpos.js" type="text/javascript"></script>
  <script language=javascript>
    getsunpos();
    document.write ("SUN Coordinates<br>Latitude: "+sunlat+"<br>Longitude:"+sunlon);
  </script>
</BODY></HTML>
------------------------------------------------------------------------------------

If you change time in your PC, then will show Sun position at new time.

Regarding MOON TLEs, I develop them monthly using moonkeps.exe a program
that I got from Amsat-Na website, and then translate to 2 lines by
KepstoTLE.exe (Due moonkeps.exe provides TLEs in Amsat format).

moonkeps is at
http://www.amsat.org/amsat/ftp/software/PC/tracking/moonkeps.zip
http://www.ne.jp/asahi/hamradio/je9pel/moonkeps.doc

On moonkeps.zip there is a DOC file with Keplerian Elements for SUN on 1995,
don't now if they are good on 2016.
Hope this is of some use.

The text were displayeda after changing the position of the double quotes.
But the value of 'sunlat' and 'sunlon' are not yet displayed on web.
I attached here one png file.

> document.write ("SUN Coordinates<br>Latitude: +sunlat<br>Longitude: +sunlon");

Perhaps I think the position of the double quotes are wrong.

----------------------------------------------------------------------------------
<HTML>
<HEAD>
  <script src="sunpos.js" type="text/javascript"></script>
</HEAD>
<BODY BGCOLOR="#FFFFFF">
  <script language="JavaScript">
    getsunpos();
    document.write ("SUN Coordinates<br>Latitude: +sunlat<br>Longitude: +sunlon");
  </script>
</BODY>
</HTML>
----------------------------------------------------------------------------------

Thank you.

Hello Mineo,
Perhaps double quotes are causing problems, try this with single quote:

-------------------------------------------------------------------------------------
<HTML><HEAD></HEAD>
<BODY BGCOLOR="#FFFFFF">
  <script src="sunpos.js" type="text/javascript"></script>
  <script language=javascript>
    getsunpos();
    document.write ('SUN Coordinates<br>Latitude: '+sunlat+'<br>Longitude: '+sunlon);
  </script>
</BODY></HTML>
-------------------------------------------------------------------------------------

Also available at http://amsat.org.ar/sun.htm
Meanwhile will try to 'invent' a TLE for Sun.

Hello Mineo,

I have developed (invented) a pseudo SUN TLEs for you.

SUN95
1 00001U 00000    95080.09236111  .00000000  00000-0  10000-3 0 99999
2 00001 023.4400 000.0000 0000001 282.8700 075.2803 00.00273790000018

They are based on 1995's seems accurate and included as SUN95.

Clicking on +Sats on http://amsat.org.ar/pass.htm, you can add SUN95
as a 'satellite'.
Don't know if other tracking programs could take this Keps.

Hope it helps,

Perfectly, I could display Latitude and Longitude of SUN
on my Java_Script web and your Sat_Passes site.
Thank you very much.

-------------------------------------------------------------------------------------
<HTML>
<HEAD>
  <script src="sunpos.js" type="text/javascript"></script>
</HEAD>
<BODY BGCOLOR="#FFFFFF">
  <script language="JavaScript">
    getsunpos();
    document.write ('SUN Coordinates<br>Latitude: '+sunlat+'<br>Longitude: '+sunlon);
  </script>
</BODY>
</HTML>
-------------------------------------------------------------------------------------

And, this SUN95 TLE is very nice.
This is properly tracking SUN on your site.

SUN95
1 00001U 00000    95080.09236111  .00000000  00000-0  10000-3 0 99999
2 00001 023.4400 000.0000 0000001 282.8700 075.2803 00.00273790000018

But, it is overflow on Japanese tracking program 'Calsat32.exe'.
This 'Calsat32.exe' can track Mars, Jupiter, Venus, and Saturn
in addition to SUN and MOON. (Already it solved correctly.)

Thank you very much for a lot of advice about SUN and MOON TLE.

[How to convert "latitude / longitude -> azimuth elevation" for SUN]

1. Write the above "Java Script" in the editor and save it in "htm" format and run it using the browser.
2. Run "Calsat32AzEl.exe" and input the latitude, longitude and distance of the sun and your latitude and longitude.
3. Enter the necessary items in the box below of http://www.amsat.org.ar/pass.htm and confirm the sun's data.
4. Show the SUN with "calsat32.exe" and confirm the sun's data.
