The 53rd parallel north is a circle of latitude that is 53 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
At this latitude the sun is visible for 16 hours, 56 minutes during the summer solstice and 7 hours, 34 minutes during the winter solstice.
Because of the far western position in the Hawaii–Aleutian Time Zone, you can even see the midnight sun so far south on Attu Island, AK, because the sun sets as late as 12 a.m. there in the end of June.
