OS benchmarks are survey marks that were used by the Ordnance Survey to make maps. They can be found on walls and buildings across Britain and were a way of recording height at a given point.Google "OS benchmark" for more information.RegardsDennis Cowan Sent from my Mobile Original message From: ro...@torrenti.net Date: 23/11/2023 06:48 (GMT+00:00) To: Sundial List Subject: Winter issue of the “Cadrans solaires pour tous” magazine Dear colleagues, I am very glad to inform you that the Winter issue of the “Cadrans solaires pour tous” magazine is now available for free download from https://www.cadrans-solaires.info/le-magazine/ Best regards Roger Torrenti --- End Message --- --- https://lists.uni-koeln.de/mailman/listinfo/sundial

The actual message text is therefore in an attachment.--- Begin Message --- The sundial was placed by the Northern Lighthouse Board, who are responsible for all Scottish lighthouses, but all the lighthouse dials were removed when the lighthouses were automated leaving only the columns in place. The sundials were then sold off. The Eshaness lighthouse was subsequently sold to a private buyer who replaced the sundial. The current sundial is therefore not original. Most well-made Scottish horizontal sundials range from 4am to 8pm, but in this instance probably a lack of knowledge resulted in the sundial that is currently in place.Dennis Cowanwww.sundialsofscotland.co.uk Facebook – Sundials of Scotlan Sent from my mobile.

They were fully aware of the latitude inclination but simply overlooked the daylight hour difference from London.

Daylength at the solstice was around 19 hours, with (civil) twilight taking up another 3½ hours or so. Here is a photo I took of a sundial at the Eshaness Lighthouse (60.489314°N 1.627209°W). Unfortunately it's on private property, so I couldn't get close enough to read the the little plaque. The current lighthouse was completed in 1929 so I guess the dial may be that early too. In Shetland the sun doesn't go anywhere near the zenith even at midsummer so I was surprised by the height of the gnomon. It's just asking to be dinged, but Shetlanders are good and gentle folk so there no sign of vandalism; just a bit of rust and corrosion. I wonder why the dial spans only 12 hours? I have seen a number of other dials that only cover 12 hours but I've never really questioned that attribute before. Of course in this case they've stuck the dial where the nearly building obscures the sun late in the day, so evening hours don't really matter. That aside, surely we should expect a dial made for such a northerly location to reflect the extreme summer daylengths? There is plenty of open space nearby where the dial could have been sited to accept sunlight throughout the summer evenings. To me it seems a trivial matter to design a dial that covers the full midsummer daylength. Can anyone justify, or at least explain, the 12 hour limit?
