re gamma ray bursters positional stuff in article apr vax mankato msus edu belgarath vax mankato msus edu writes getting at here this puppy is far enough away that if a bright burst happens nearby the huge annulus created by it will hopefully intersect the line or general circle given by batse and we can get a moderately accurate position say oh or degrees that is the closest anyone has ever gotten with it you can do a whole hell of a lot better than or degrees with the differential timing measurements from the interplanetary network ignore the directional information from batse just look at the time of arrival with three detectors properly arranged one can often get positions down to arc minutes btw about oort cloud sources shouldn t this be testable in the fairly near future some of the grbs have very short rise times ms we could detect the curvature of the burst wavefront out to a distance of on the order of b t c where b is the detector spacing and t the time resolution for t ms and b au this is on the order of light years i understand statistics will reduce this number considerably as would geometry if the burst is coming from the wrong direction paul
