Don't worry it is just a meteor shower! The Perseid's spark a lot of interest in the astronomical world. (Well at least I think the do). They have some really nice pictures at NASA. The picture below is also from NASA.
As long as there is little to no clouds, you should be able to see a good meteor show, but do try to stay away from the city lights. You can always check the Norwich weather here.
In my day Pluto was still a planet... which makes me wonder if all the books at Otis are up to date, and if we have taken out the "Pluto as a planet" references. Hmm, we'll have to see.
Anyway, for all of you Norwich residents who are looking for something to do between 2:00 am and 4:00 am on August 12th, go outside and see a meteor shower! Unfortunately, I can not tell your boss that you are excused from work because you are too tired from becoming astronomically educated.
