The graphic below shows some of the AIS position reports received in the last two days.
The Red tracks are nominally 203°T , the Yellow tracks 024°T, and the most recent Green track is 293°T. The TPL towing has been carried out at 2.0 KTS at all times, with small increases of speed showing up during the turn and realigning phases.
Though the JACC aren't saying anything at this stage, it appears that an attempt is being made to triangulate and localize detected pings.
