Abstract

Threadlike streamers have small cross sections that are almost constant over their whole length. A typical value of their diameter is 30000 km. Threadlike streamers may reach a length of several hundred thousand kilometers or even more than a solar radius. A photometric analysis of a threadlike streamer, observed at the eclipse of 1963 July 20, yields an electron density 8 times larger than that of the undisturbed corona. This ratio undergoes only small variations with the distance from the Sun.
