Rear curtain sync...

the flash is triggered just before the shutter closes, so you have movement and then the final position is fixed on the sensor. It's a very nice effect with slightly longer shutter speeds and moving objects (1/50 and lower).

If you have a long exposure you get blur from a subject in motion. If you also fire the flash it activates at the beginning of the exposure. The result is a clearly illuminated subject with motion leading out of this point in time. That looks odd.
Rear Curtain Sync fires the flash at the end of the shutter interval. The result is a nice motion trail behind the subject, which looks more pleasing to our eye.
Use Rear Curtain Sync when all of the following are true:
* your subject is moving
* your shutter speed is relatively slow
* you are using a tripod (needed for long exposures in any case)
