Why the giant arrow on Titan?

Why does Saturn's moon Titan sport a giant arrow in its atmosphere? By the time you read this, it doesn't: it's a transient cloud pattern caused by an interference pattern of atmospheric waves. Either that, or aliens posted it to point spaceships to Saturn, as if they otherwise would not notice the gas giant planet dominating the horizon. Either way, it's kind of a mind-stopping image: after all, we KNOW moons are not supposed to have arrows as big as Texas on them.
