It might be useful to determine the rate of the sun's movement at the ends of the analemma. There is a passage grave north of Dublin, Ireland, that has a long passage from a shadow box above the entrance to a spiral carving on the rear wall. Light shines on the carving at the winter solstice. The waiting list to see this event fills up with New Agers about a year before the event. I asked our guide if that wasn't very hard on people who could only see the event on one day if that day was cloudy. "Oh, no," she said. "The event happens for 3-4 days on either side of the solstice." Of course, a passage grave is not the same as a shadow cast by a fine wire on a microscope. It might take a few years to locate it properly. Are there any timenuts that want to be buried in a passage grave?

I still think it is "one". because there are not an integer number of days per year so you don't get and exact repeat in 6 months. Maybe a pin hole would only work once ever? I don't know. To "work" the pinhole has to exactly line up with the detector at the exact same time of day. But I'm not liking slits either because I can't see how to adjust them to exact vertical. I'm back to the first thing I thought of, a wire with a large weight. Then you measure the light curve as shadow of the wire sweeps over the detector.

At the solstices, the derivative of the declination goes through just about to zero, just like a sine wave. -John ============== > It might be useful to determine the rate of the sun's movement at > the ends of the analemma. > > There is a passage grave north of Dublin, Ireland, that has a long > passage from a shadow box above the entrance to a spiral carving on > the rear wall.

For those unfamiliar with horology, look at the Wikipedia under "equation of time" This is the relationship between solar time and the average or "mean time". It is mainly the sum of two sine functions, one of 6 months frequency the other one year. Amplitude 16 - 17 minutes. This function allows a mean time clock to show the time of noon each day (passage of the Sun through the meridian) cheers, Neville Michie On 24/01/2012, at 3:59 PM, J.

In such a way we will achieve the very 11-ness of timing. We must, of course, enclose it to make sure that it's not crushed by dancing dwarves. (couldn't resist)

I used the equation of time and the audio from wwvb to align loop antennae to n/s and e/w using the shadow of one vertical arm on t'other at local noon. Worked amazingly well.
