LUSTRATIO SOL ???!!!
My late professor of latin is actually tossing in his grave!
In Latin, this is a nonsense. The word SOL is in the nominative case, but here you must use the genitive case, SOLIS. So, lustratio Solis, or, even better, Solis lustratio, because in Latin the genitive usually is before the word which it refers to.
I can't believe that in such a posh school as Veridien they could make a mistake like this.
