While it happens every year, it’s still worth seeing as the peak time falls on a weekend this year.
The peak time for the shower will be early Sunday night/Monday morning (2 am), but it will be going on Saturday night too, which is when I’ll probably head up to the roof to see what I can see.
Should be a hell of a good show.
