flocculi's Usage Examples:

including prominences, spots, faculae and flocculi, and p even the eleven-year period.

Neither the forms nor the motions of the calcium flocculi revealed the existence of such b

They also show less extensive bright flocculi, usually in the immediate neighbourhood of sunspots, and frequently eruptive in character.

These reveal dark hydrogen flocculi, which appear to lie at a level above that of the bright calcium flocculi.

Photographs of the solar disk, taken with the H or K line, show extensive luminous clouds (flocculi) of calcium vapour, vastly greater in area than the sun-spots.

The calcium flocculi, on account of the brilliant reversals of the H and K lines to which they give rise, and the protection to the plate afforded by the diffuse dark bands in which these bright lines occur, are easily photographed with a spectroheliograph of low dispersion.

The forms of these flocculi show that all sun-spots are vortical in nature, and are probably analogous to terrestrial cyclones or tornadoes.

On account of the relatively great strength of Ha at a considerable distance from the photosphere, the new photographs recorded flocculi at high levels previously unexplored.

But the beautiful currents, but in the higher region shown by the hydrogen photographs the distribution of the dark flocculi suggested the operation of definite forces, though their nature remained obscure until the spring of 1908.
