  On June 25, 00:24:33 U.T. a GRB (GRB990625) was simultaneously detected by the GRBM and WFC aboard BeppoSAX (also BATSE trigger 7619).
  Unfortunately the attitude configuration at the time of the GRB does not allow to reconstruct the GRB position to better than about 1 degree radius. The estimated position is (Equinox 2000):

  R.A.=6.64
  Decl.=-31.2 

  Due to the large error box, BeppoSAX is not going to observe this location with the NFI.
