Do you think it is easier to remember the constellation name or the number of the constellation? In my opinion most people will prefere the names. By the way it is very difficult to change the names. The constellation names are historical, hundreds of years old, and lots of "normal" people know the constellation Andromeda, but only some thousands will know the star 100001 (R And). It is very stupid to discuss the number of leading zeros in a star name. You can write a simple computer program which is able to use "AndV000123", "V123 And", "ANDV123" and "And V00123" for the same star. My own observation database does this, I implemented a function to scan the vsnet-obs mails, and it works for more cases than the above mentioned. E.g. novaes: "N1999#2 Aql" = "Aql Nova 1999#2" = "AqlV1494" = "V1494 Aql" ... Regards, Thorsten Lange -- Thorsten Lange EMail tl@thola.de http://thola.de/
