If the sun disappeared, just vanished, would we be able to tell something has happened before it all goes dark?

If some weird cosmic event made the sun disappear, presumably, it would take 8 minutes before the lights went out on Earth. However, are there other effects we would notice before the lack of sunlight became apparent, for instance, how quickly would the Earth hurtle into space on a tangent to our normal orbit.

According to general relativity, gravity also propagates at the speed of light, as does any other information we could measure about the Sun. Unless we had some way of detecting the event that was about to cause the sun to disappear, we wouldn't notice it until 8 minutes later.
