It is a shadow. How exciting can that really be?
I’ll try to explain it to you. One minute the sun is shining so bright that you can’t look at it, although things are getting darker, like someone is turning down the lights. And then, suddenly it is night time. Not the middle of the night, but night nonetheless with stars out and everything. And where the sun was is a white glow surrounding a pure black disc. It is quite impressive. I really enjoyed it.
