That's me, I wrote and maintain the scripts that create the files on the FTP site from the Keps bulletins published by Ray Hoad. Thanks for pointing out the problem.

The script that creates the nasabare.txt file simply scans the nasa.all file and copies out everything that's a valid 2-line element set. The nasa.all file, in turn, is created by saving everything between the SB line and the /EX line in the bulletin email message, just as a packet radio BBS would have done.

The error this week is actually in the bulletin text itself. Many of the element sets in the bulletin were mangled for some reason. You can see this easily by noting that the line lengths are not all the same, as they should be.

I have replaced both nasa.all and nasabare.txt with versions from last week's bulletins. When Ray publishes a new set (usually on Friday), they will be replaced as usual with the latest info.
