Thanks for those updates, Christophe. So sunset would be not 15.38, but more like 17:20 (5:20 PM) and moonrise would be not 23.17 but more like 24.00 (midnight). Sunrise, as you say, would be 5:24 a.m. If the aircraft landed on the western side of Nikumaroro, then the trees and bush would, to some degree, block the light of the moon rising toward the east even further. Referring to the Tides & Credible Signals report prepared by Bob Brandenburg in Volume 28 #1 of Tighar Tracks, the radio signals started about 7:00 pm and continued to about 11 pm (July 2-3), from about 9:00 pm to 1:00 am, with another scattering at about 5:00 a.m. (July 3-4). and from about 7:30 pm to about 3:00 am (July 4-5). So these were essentially moonless dark nights in which they would have to make their way across the reef to find the aircraft. Just getting to the aircraft to make these radio calls could not have been easy. / Scott #3292
