    Re: The last transit of Mercury for 26 years
    From: Frank Reed CT
    Date: 2006 Nov 5, 18:35 EST
    For observers in North America, especially, there's a nice little map and some other observing info on the "Sky & Telescope" web site here: http://skytonight.com/observing/home/4548556.html
     
    From here in Chicago, the transit will be visible for about 3 hours, 20 minutes before the Sun sets. The apparent diameter of Mercury transiting the Sun is something like 9 arc seconds, 200 times smaller than the Sun's apparent diameter. That's just barely visible through a sextant (shades down) if you have a moderately powerful telescope attached.
