Sirius' Name

Hey guys, just a quick question.  Is Sirius pronounced like the word
Serious?  For some reason I have pronounced the name in my head as 
Sirus.  For some reason whenever I read his name I guess I would 
subconsciously eliminate the second I.  Similarly I always read 
prefects as perfects.

he is still gone)
