A negative charge is coming towards the observer. The direction of the magnetic field produced by it will be (as seen by observer):
A negative charge moving towards the observer is equivalent to a conventional current moving away from the observer. By the right-hand thumb rule, if the thumb points away from you, the fingers curl in the clockwise direction.
