Use an when the following word starts with a spoken vowel.

Nightmare85's "a/an alphabet".
Whenever you use abbreviations like:
An HTML site, An MPUK admin, A URL, A UFO, An SSE4.1 compatible CPU, An SQL server; you must simply remember that alphabet.
It does not matter how the long version of an abbreviation is!
A UFO -> An unidentified flying object; but not An UFO!!
