CREATE TABLE table_4566 ("Higher harmonics" TEXT, "Darwin" TEXT, "Period" TEXT, "Speed" TEXT, "Doodson coefficients" TEXT, "NOAA" TEXT)

What is the speed of the higher harmonics that have an NOAA of 37?
SELECT "Speed" FROM table_4566 WHERE "NOAA" = '37'
SELECT "Speed" FROM "table_4566" WHERE "NOAA" = '37'
