The flag of the Federated States of Micronesia was adopted on 30 November 1978. The blue field represents the Pacific Ocean. In an echo of U.S. heraldic practice, the stars represent the four federated states: Chuuk, Pohnpei, Kosrae and Yap, arranged like the points of the compass. The four white stars are oriented in a circle with none of the 'rays' pointing inwards, adorning a shade of blue representing the Pacific Ocean. The ratio of the flag is 10:19 and the width of each star to the flag is 1:5, though it is permissible to reproduce the flag in other dimensions for unofficial purposes.
