Scientific paper

The H-alpha observations of a flare-associated surge prominence on Oct. 30, 1980, have been described. Morphology and dynamics of the surge prominence have been presented. From the observations and analysis, the magnetic field associated with surge material is estimated to be about 35 gauss, which is in good agreement with the earlier result of Tandberg-Hanssen and Malville (1974). It has been determined that coronal pressure is not acting as a resistive force on the outward expansion of the surge into the corona. The kinetic energy of the surge was about 10 to the 28th erg, which is two orders less than required for the mass to escape the chromosphere. It appears that the flare-associated surge prominence was perhaps a result of kink instability in the flaring region.
