Abstract
Oblique incidence radio observations on sporadic E reveal both the movement and geographical extent of these reflection areas. On 13 June 1949 two Es centers were observed by this method. The first sporadic E center developed rapidly until it included an area of over 106 km.2; the second Es center was much smaller. The velocity of the center of mass of the first area was about SE 100 km. per hr. (in the meteorological usage; i.e., from the SE) and the velocity of the second, about SSE 270 km. per hr. Drift velocities in the ionosphere obtained by other investigators are of about this order of magnitude.
