    2016 Nautical Almanac
    From: Stan K
    Date: 2016 Jan 8, 20:32 -0500
    Has anyone else noticed that the 2016 Nautical Almanac (Commercial Edition) has six new pages on Polar Phenomena?  Two pages of explanation, one page of Semiduration of Sunlight and Twilight, and fthree pages of Semiduration of Moonlight.  They cover latitudes of 65º to 90º.  Makes me cold just thinking about it.
