This number 17.33333t is the distance between SH and Avebury in miles noted in my sexond book, I did not know why it was this distance but it seems obvious now.
It is 52 x 1760 feet (1760 / 12 = 146.666r) the eclipse prediction unit absorbed into the eclipse danger warning period.
The line of 17.333 miles has an exact back bearing from SH of 176 degrees. ( 12 x 14.666r )
This number 520 is soli lunar as 52 x 7 solar and 520 x 2/3 lunar and is the denominator in the Thom Pi approximation. It is eveidenced at SH in an unpublished StuKeley sketch I presented to the archaeos on the megalithic portal with the predictable zero response.
