Cape Bolton NK to Mount Chōkai Jp

"Obviously, those mountains which we saw so clearly on the solar disk had to be on a line between us and the rising sun. And, indeed, by constructing on a chart the aforementioned azimuth of the sun at the moment of its rising, it turned out that this line passed just through the high mountain Tonvumi-yama , located on the north-western part of the Japanese island of Nippon [sic -- he means Honshu], at north latitude 39° 5' and east longitude 140° 10', not far from the city of Akita. The distance from the cruiser to that mountain was 480 sea miles." An accurate calculation gives 897 km or 490 nautical miles."
