Striped jelly Port San Luis, CA, USA

Washed up on Olde Port Beach in Port San Luis. Photographed at 12:42 tide was approx 2.7 ft. Dark red/purple stripes on top side of crown. Approx 12 inches across. Typically only see Velella and moon jellies on this beach. Lots of sea lettuce washed onto the beach during the high tide overnight before. I have a second photo with some of the top if you need it.
