Re: Newbies request for help again
you can find when the Sun is due south using Stellarium. Include the meridian line - under the Markings page accessed from the left hand vertical panel - and expand the region around the Sun so that, by adjusting the time, you can see when the meridian line cuts across the Sun and the time will be when the Sun is due south. At this time a shadow will point exactly true north.
Stellarium showed that today, the Sun will be due south at 17:35 UT.
