I make the 'impact' point on the moon about W 2, S20. In the highlands a bit south and east of Arzachel. The red corona, or whatever it is, is about 20 degrees across, getting on 400 miles I reckon. Vaporised surface, ejecta, heated surface, who knows, but if the latter that's a mindblowingly huge energy release. The actual impact phenomenum, crater or whatever, well hard to be accurate about 3 pixels, but certainly not as big as Tycho. Could be 20 miles across? That has, as they say, left a mark.
As for what it signifies, who knows, we shall just have to wait and see. I don't think I see an interplanetary/orbital war scenario though, it doesn't feel like the writer's style to me.
