I recently went down another rabbit hole that I had been intending to go down for some time. This one was about trying to create a list of the 40 stars in our Galaxy that exhibit the largest yearly proper motion. It wasn’t easy since I had to blend three different sources. The first one I used was a list of the 150 largest proper motion stars in the Hipparcos Catalogue. Then I added the fainter stars from the LHS Catalogue, 2nd Edition (Luyten 1979). Lastly, I added even more recent finds from the 2012 edition of the RECONS Project's "List of the Nearest 100 Stellar Systems". Maybe someday I’ll get around to creating a PDF finderchart for each one (or you can!), but for now I’m just happy to have gotten accomplished what I did.

 

So, I hope you all enjoy it and can make use of it. Due to their special nature, I have always been fascinated by the highest of the high proper motion stars in the sky. That’s why I wasn’t surprised to find that after assembling the list, I had already seen half of them already! But now I can make a point to try and see the rest on the list.

Nice list! 

 

But there's an error in the spreadsheet: Stars south of the Equator are missing the -  sign in front of their declination. 

 

 

Clear skies!

Thanks for pointing that out, Thomas. The "minus" symbols displayed just fine in Excel, but I didn't notice that Google Docs didn't recognize the type I used. So I found a type it did like and have updated the spreadsheet. Please do let me know if you find any other mistakes!
