As night approached, there were signs that the whale may have been swimming with the current out of London towards the sea: an unconfirmed sighting by a BBC cameraman at 9:00 pm placed the whale in Greenwich. The area was searched but nothing was found. There were no further official sightings until 1:10 am the following morning in Battersea, after the tide had changed. The whale was monitored until 3:30 am, when Jamie Henn, a Marine Mammal Medic working for BDMLR finally called the monitoring off as the whale would not strand at high tide.
