A piece of pi

This crop circle from Barbury Castle (1 June 2008) represents the first ten digits of Pi: 3.141592654 and was in much of the British press.  It was an astrophysicist who made the connection.  I wonder if he made this connection too?

It was cited as being a masterpiece because multiples of the same angle (36 degrees) were used.  I wondered why 36 degrees.  After all, the artist could have used other numbers just as well like 18 and 72 (half and double).

Note the tramline running across the centre.  It intersects with the numbers 5, 6, 9 and 4 on one side and 5, 9, 6 and 4 on the other.  Both sides add to 24 (as in hours in a day) which made me wonder if it signified a date.

It does, so it seems.

The star chart is of 28 November 2012 at 23:11 at 53N 0 32W.  The "ratchets" align with the planets, moon and sun.  The "decimal point" aligns perfectly with the Winter solstice.  The yellow tramline aligns perfectly with the horizon.  The "path" (in pink) aligns with Neptune and also intersects with the 33rd "segment" (of which there are 40) of 36 degree angles.  28 November has 33 days after it to the end of the year.

The circle was reported as being 150 metres or 494 feet in diameter.  That makes a radius of 247 feet.  The sun's ecliptic coordinates on this day at this time are 247 degrees 8 minutes, 0 degrees.  The sun is at 247 degrees only one day a year.  This year it is 28 November.

The circles measured 516 inches (centre), 416 inches, 320 inches and 200 inches in diameter.  

516 inches is exactly 43 feet.  That makes a radius of 21.5 feet; the declination of the sun at 23:11 on 28 November 2012 is exactly -21 degrees 30 minutes.

416 inches is 34.67 feet.  That gives a radius of 17.33 feet.  At 23:11 the azimuth of the sun will be -17 degrees 20 minutes.

320 inches is 26.67 feet or a radius of 13.33 feet.  The altitude of the sun at sunset on 28 November 2012 at 1551 GMT is 13 minutes 20 seconds.

200 inches is 16.67 feet or a radius of 8.33 feet.  At 16:43:48 the altitude of the sun will be -8 degrees 20 seconds.  This is exactly the same time as I mentioned in a previous post with another crop circle which had the declination of sun at 21 degrees 27 minutes:

If we add these to the diagram we have the following:

Look at the three circles on the outer edge.  The number 6 starts where Venus is and attaches itself to the third circle (marked "Solar Event") if counting from the largest downwards.  As we saw in a previous post, the estimated time of the event is six hours after Venus.  This ties in with that.

It certainly isn't as easy as pi to swallow...
