| Abstract: | The null surface method and the York method in general spherically symmetric or plane symmetric non static space times are discussed.It is shown that the null surface method is highly effective for determining an event horizon. Besides,a set of useful approximate values of the Vaidya Bonner de sitter event horizons are given. |
