    Bonjour Kermit,

    I did not go as far as iterating on UT to find the moment in which Navigation Spreadsheets think the apparent Venus-Mars distance is minimum. However, I was pleased to see the same angular distance of 24.7’ come out for the time instant that you specified.

    I will address your Moon example (in relation to Uranus) in a separate message.

    Hello to all,
    1 - Looking up my cristal bowl, I can see that on Feb 22nd, 2015 by 06h24m29.7s TT (i.e. approximately 06h23m25s UT1) the Geocentric angular distance/separation between the centers of Venus and Mars will be minimum and close to 1,481.2 " (24.7') i.e. less than the Moon or Sun Diameter seen from Earth . And,
    2 - Likewise, on Feb 21st, 2015 by 03h00 UT, and observed from a position in the vicinity of N35°/W135° Venus, Mars and the New Moon should be visible in a quite narrow circle, less than about 1° radius. And,
    3 - From that same N35°/W135° Position, on Feb 22nd, 2015 by 03h00 UT, i.e. in the evening (and maybe also for the next following 2 evenings) Lady Moon, and Venus / Mars should be in a configuration for a double simultaneous Camera Lunar (Moon and Mars/Venus {at} 15° degrees apart). 
    This brings up 2 questions:
    To you NavList Colleagues - Paul, Peter, Andrés, (and Hewitt, and others ?) - and in relation to point 1 hereabove, what does your own cristal bowls say regarding the upcoming time and minimum geocentric angular separation between the centers of Venus and Mars ? And,
    To you my Dear Greg, any opportunity for an historical picture on Feb 21st, from California in the evening, and for a double simultaneous Camera Venus Lunar and Mars Lunar in that same Feb 21st evening, or in the evening of Feb 22 nd ?
    Thanks to all for your Kind Attention, thanks in advance to whoever will give his own reply to point 1 here-above (such reply can also and rather easily be dug out from a plain Nautical/Astronomical Almanac).
    Kermit

    PS: Hopefully no-typos here-above. They usually show up ONLY AFTER I hit the "launch" button, and almost never during the previous proofreading examinations.
