Question 1

Where is SYDNEY ALYSSA II right now?

Accepted Answer

SYDNEY ALYSSA II has not broadcast an AIS position for 135 days. The most recent broadcast placed it in the North Pacific Ocean, on 26 Apr 2026, 12:15 UTC. It was sailing from DAVAO to DAVAO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for SYDNEY ALYSSA II?

Question 3
