solar twin?

I have read that star hd 143436/hip 78399 may be a very close match to
sol,and is not extremely distant to boot.However I haven't been able to
find a finder chart online.The article I read indicated that it is
within range of binocular observation but left it at that.I do have a
couple of planetarium programs(ie cartes du ciel)but no luck.If anyone
else is interested in this ,or has info on where I should look I would
greatly appreciate it .Thanks

Does this star have another designation? I'm not finding it anywhere.

The standard installation of Cartes only has a catalogue of stars down to
mag 6.5, you need to download the other (deeper & therefore bigger)
catalogues (and indexes) separately. I have sky2000 and the HD index and
found it. Check out the Cartes downloads page for details.

For anyone interested this is the article in Astronomy:

Same article on the author's page has a link to the original research:

I found it on starry night 4.5 using it's alternate name - HIP 78399.

Here is some more information on the star from the Hipparcos catalogue:

Here is some photmetry data for the star:

And here is the star:

I will be doing some observing with my brother and a couple of very
experienced friends Friday night. It might be an interesting object to try
to find and photograph. Will keep everyone posted. Wish me luck.
