    who has A Moondial?

    https://en.wikipedia.org/wiki/Moondial

    It is like a sundial but using the moon, at night.
    Formerly Frog march.

    Newscaster: ... But I've just had a report that a representative of Disaster Area met with the environmentalists this morning and had them all shot, so now nothing stands in the way of the concert going ahead this afternoon on this beautiful sunny day.

    I used to be able to tell time by looking at the North Star and the various circumpolar stars--took a little calculating, but I could get within ten or fifteen min without a lot of trouble

    I've never knowingly seen the North Star, but I read, the other week, that if you follow a straight line through the two right-hand stars in The Plough, that it will pass close to the North Star, so I must try that sometime.

    The North Star is mag 2, so it doesn't necessarily jump out at people

    Remember, sometimes those two right hand stars are to the left (when it has rotated upside down), or even up or down.

    If you look shortly after dusk at this time of year (weather permitting), the Plough (the Big Dipper as we Americans call it) will be off to the left of Polaris, with the guideline from those two stars going up and to the right. Follow that line about 5 times the spacing of the stars and it will pass close to Polaris.
