A micropulsation experiment has been in operation since December 1964 near the magnetic poles at Camp Tuto, Greenland, and Vostok, Antarctica. The purpose of the experiment is to investigate the character of micropulsation activity in the polar region, where field line conjugacy probably does not exist. Examples of some 'pearl' micropulsations observed simultaneously at the two sites are given. Preliminary measurements of the delay time between reception of pearls at College, Alaska and Camp Tuto, Greenland indicate that these emissions originate in the auroral zone and propagate away from that region in an ionospheric duct.
