    Re: Could I have seen Mercury yesterday evening?

    For the best way to see Mercury, you compute its distance from the Sun, and 
    search in the computed direction
    with a binocular. Once you found it and know where it is, you can easily see 
    it with the naked eye, if the distance from the Sun is large enough.
    I did it successfully. The main thing is to know where exactly to look.
    Same works with Venus. You can see Venus while the Sun is still present.

    Subject: [NavList] Could I have seen Mercury yesterday evening?
    Yesterday evening I tryed to have a look at Mercury after the sunset. 
    Unfortunately, there was a cloud band just above the horizon - I could see 
    the Sun going down the horizon, I could see some sky above the cloud strip, 
    above which there were some clouds again. I.e. there were two "windows" - one 
    ON the horizon, ~2  wide in vertical direction, then the cloud strip also 
    ~1.5 ~2.5  wide, then another patch of the sky also ~1.5 ~2  wide.
    Few moments after the Sun got under the horizon - I could see some planet in 
    the upper "window". It was reasonably bright. Since I'm at 60 N - the Sun 
    goes down rather sideways, so I could not tell whether that planet was 
    immediatelly above the Sun or it was to the left of it.
    From NA I know that Venus is near the Sun-Earth line, and Mercury is on the 
    east elongation or thereabout. So I want to know which of the two planets it 
    could be I was looking at?
    I never saw Mercury before - at least knowing for sure  it was Mercury. How 
    bright/dim is Mercury on max. elongation compared to Venus's dark side?
    Warm regards,
