FTP access at Lowell Observatory has been discontinued, therefore the file “astorb.dat” can’t be retrieved anymore by Uruk_One. In few days a new version of Uruk_One fixing the problem will be released. In the meanwhile the file can be manually downloaded and placed into the USER_PATH.
Here’s what they say about this change:
“astorb.dat and astorb.dat.gz have permanently moved to https://ftp.lowell.edu/pub/elgb/astorb.dat and https://ftp.lowell.edu/pub/elgb/astorb.dat.gz, respectively. FTP access is no longer supported.”
