Description:

"Solar filaments are readily detected in H[alpha] observations of the Sun as either extended, dark features seen above the disk, or as bright prominences seen above the limb. They vary enormously in size, from fine, dark features of a few heliographic degrees in length, within active regions for instance, to very large structures exceeding 60 heliographic degrees which overlie the quiet chromosphere or the spotless remnants of active regions. Filaments always lie above magnetic inversion lines, which separate regions of opposite magnetic polarity in the photosphere, although not all inversion lines are marked by visible filaments. There fore they enable the broad features of the large-scale magnetic fields at photospheric and chromospheric levels to be mapped from routine H[alpha] photographs (McIntosh, 1979)"--Introduction, paragraph 1.
