I would say so! Good grief. At magnitude 22.2, "shines" just doesn't sound right.

Let's see here. Mr. Sun is magnitude -26.7. So halfway between that and Caliban's 22.2 is magnitude -2.3. That's brighter than the night time stars, but not a whole lot, so -- what? Jupiter or Saturn, maybe? So this object is about as many times dimmer than Jupiter or Saturn, as they are dimmer than the sun.

It reminds me of a light bulb in the movie Mr. Hobbs Takes a Vacation, of which the title character says something like, "if you turn it on, the whole room goes black."
