Hmm… I think this is similar to the lie/lay quandry. Use ‘raised’ if something external was doing the raising, but use ‘rose’ if it was an act of the thing itself.
The Columbia Guide to Standard American English says:
raise 2, rise (nn., vv.)
Rise (rose, risen) is almost always intransitive: The river rose overnight. Prices have risen again this month. Raise (raised, raised) is usually transitive: We finally raised the money. Raise also has some intransitive use, most of it dialectal or otherwise Nonstandard, but some of it fairly widely heard, particularly in sentences that drop the reflexive pronoun, such as She raised [herself] up on her elbow in bed to peer at the clock. Even Standard users sometimes use raised this way, but only at the lower levels of speech, and other Standard users can sometimes be highly critical.
