Abstract

Observations of a surge prominence event on 31 May 1971 are discussed. The continuum emission observed during the upward acceleration of the surge is attributed to the scattering of photospheric radiation by free electrons. The observed scattered light intensity amounts to a few times 10−5 that of the central disk intensity leading to a column density of n e L≈1020 cm−2. The actual electron density when taking into account the presence of inhomogeneities is n e ≈1012 cm−3. The dynamic and morphological behaviour of the surge is considered.
