Setting accurate South/North line for Pier/Tripod

[mikerr]

Looking at Als Astroclock clock this morning shows that today the Solar Noon will be about 45 seconds before local noon here.

I intend to try and use the string and plumbob method of marking a North/South line on my water tank where the new pier is going.

It will be interesting to see how different that turns out compared to the magnetic compass method I have been using to position the tripod.

I also figured that as the Solar and Local noons were so close together today it must have some significance.:question: Looked up Winter Solstice and Hey
it turns out to be around 20th of June. Tomorrow!!!:D

Thanks for the heads up, Mike. I went out at noon and checked my carefully calculated N/S marks and they were out by a goodly number of degrees.
(Not saying how many - too embarrassed)
