AAVSO Acronym of the Day: AUID

Today's AAVSO Acronym is AUID – AAVSO Unique Identifier

These combinations of numbers and letters uniquely identify all RA/Dec pairs in VSD, the AAVSO Variable Star Database. They come in the form of triplets ###-XXX-### (101-BCD-854). Triplets are easy for humans to process and they are easy to type. No vowels are used to prevent words. This allows for 10 billion combinations. These identifiers are assigned to variable stars, suspected variables and comparison stars in VSD. Data cannot be submitted to the AID unless an object has been assigned an AUID.

This is just one example of the tools and programs the AAVSO provides to its members, observers and the astronomical community. Please help support these services by contributiong to this year's Annual Campaign.
