I guess the full moon will just look more impressive to most people.
There's a lot of hype about the standstill this time but what about last time. I wonder if anything interesting was noted 18-19 years ago, not just at Callanish but other places as well. The Avebury and Stonehenge 'architects' would surely have known about the 18-19 year lunar standstill cycle and I wonder if anything of special interest happens at those places at those times as well.
