Özet
A helical surge (S 72, W 90) was recorded by a monochromatic filter at the University Observatory of Istanbul. It is a significient one at a very high latitude and without any center of activity. A sequence of the filtergrams showed some condensed points from which the motions &the plasma are traced. Different velocities were determined on each of the branches of the helical surge during its evolution. The surge reached its maximum height of 298 000 km and the maximum velocity of this upper region was 250 km/s.
