The shower may last that long but it won't do a thing for any HF communications. May 24'th is my last day off and I have to get up early May 25 however I may still stay up for a while and have a listen for any Ms pings. The thing about meteor scatter (Ms) is that it happens 24 hours a day 365 day of the year as there is always something streaking past however meter showers are when activity really picks up. I just don't know if I will have the stacked 13B2's up by then.
