Howland's official location is now
0° 48′ 25.84″ N, 176° 36′ 59.48″ W
This is what Randy Jacobson had to say on the subject:
"As for the erroneous Howland position, Bill Miller, when he first worked the
Line Islands (Howland, Baker, and Jarvis) colonization scheme in 1935/36,
was the one who reported to the CG and US Navy the revised position.
Richard Black, his successor, also knew of the revised positions. Bill
Miller was AE's technical liason with the US Gov't for planning the first
flight. I find it absolutely inconceivable (but undocumented) that he did
not provide her with the revised position. It was only "classified" until
such time as the US Hydrographic Office could update their charts, which was
done in 1938. It was not a true secret or classified piece of information
in the strict sense of the word."
And yet, Miller's April 5, 1935 report to the Treasury Dept. (Coast Guard) on Howland Island, written at sea en route to Baker Island having just left Howland, gives the island's position as 0° 49' N 176° 43' W - the erroneous position used by Williams. The correction must have come later.
