AMSA have recently defined the search area as within a circle of 10km radius centered on the 2nd ping detection. That area is defined by the White circle on the graphic below. The rectangular area on a major axis of 030°/210° represents what previous AIS position reports indicate the area the Bluefin 21 AUV is working in. Each days positions are a different color, and the first position for today (20/04:03z) is shown in a Cerise color.
The Red stars represent when pings were acquired, and the sequence is numbered anticlockwise starting at the top. The White star is the position that the pings associated with the first ping were lost (LOS).
