The photo of the tower shows an interesting reflection on human life. The people in the penthouse flats are still out making money (or partying). The managerial classes on the mid levels are just coming home, and the workers in the lower levels are already in bed or down the pub. Is 'but you may have forgotten over the northern hemisphere summer' a red herring? Orion is upside down. Well, he is to me used to seeing him from the UK. How would he look to people who live upside down themselves i.e in the Southern Hemisphere? Is upside down to me the right way up to them?
Where I live you have to follow his sword right over the top of your head to find north, but in the photo you only have to go down to the nearest horizon. Also, that belt (the three brighter stars) is pretty much on the celestial equator, so can we get approximate latitude from that? At the Earth Equator the belt would be overhead at local . At the South Pole it would be on the horizon all night, so should we be looking at latitude = 90°-the height of the belt at or thereabouts? But we need the time. Can we tie this in with the line of the sword moving anticlockwise like the hour hand of a clock in a mirror? OK here we go. The sword is at 45°, so it’s local. The belt has about half as far again to rise before . It’s about 30° now, so it’s going to rise to 45°. Therefore were at 45° S looking north (which isn’t quite where Google says the termites live) DaveP
