    Re: How often can you see the sunrise/sunset - PLEASE HELP?

    Correction, for a cloud 2-5km the hole in the cloud to see the sun at
    midday (i.e. straight overhead, assuming straight edges) would need to
    be 47m at the top (19m at the bottom)
    
    And the point was that a 50m hole is a lot more likely than a hole
    some 3000x bigger or 150kms across!
