I have ascertained that on January 19 at 0200 UT the colongitude of the terminator will be at precisely 358.0º, the perfect position for viewing the Werner (or lunar) "X" at 6:00 p.m PST on the evening of Friday, January 18. However, I understand that another condition for this is that the altitude of the rising sun at the crater Werner should be about 1.5º. Can anyone advise how and where I can find information indicating the altitude of the sun at 0200 UT on January 19, 2013 at colongitude 358º?
