The report is dated 15 May 1879 and comes from HMS Vulture in the Persian Gulf. The crew described luminous pulsations moving through the water around the ship and then two revolving wheels of light. Each carried illuminated spokes and the two turned in opposite directions to one another. That is the entire description the archive holds.
What is on the record
One telling, one video, one reporting channel. The archive resolves two claimants: J. E. Pringle and Captain Evans, whose name the file marks as reported rather than as a direct account. No documents are held. The ship's log and any contemporary publication are absent, so a nineteenth-century naval report reaches the archive only through a modern retelling of it. The country field for the entry is empty and the position is given simply as the Persian Gulf.
Two things keep the record from being wholly isolated. The archive holds two further sea light wheel entries, from the SS Patna in 1880 and the SS Bintang in 1909. That places the Vulture report inside a small recurring class rather than standing alone. Luminous displays in seawater also have ordinary causes that the file does nothing to rule in or out, since it contains no measurement and no assessment of any kind.
Why it sits where it does
The entry carries an L3 label on two claimants attached to one event, which is generous for what is here. A single channel carries it, one of the two claimants is secondhand within the telling, and the case is thin by any reading. What the archive can show is that the light wheel report from HMS Vulture has survived into the modern literature and sits alongside similar reports from other ships across three decades. What the crew of the Vulture watched is not resolved here.
