The only sighting referenced is on page 40 of http://permanent.access.gpo.gov/websites/pollux/pollux.nss.nima.mil/NAV_PUBS/SD/pub126/126sec02.pdf and shows a date of 1926. The topographic data supplied by http://www.gebco.net/ and accessible via http://www.wolframalpha.com/entities/undersea_features/filippo_reef/q1/il/vm/ however shows a sea depth of 3.3 miles. It is therefore likely that this 1926 report is an error, and that Filippo Reef is a phantom island, and that therefore any maps showing it are relying on the 1926 report, and are also in error.
