Streamers


These long finger–like strands near equatorial regions and short fan–shaped appendages near the poles of the sun align themselves with the sun’s magnetic field. They also vary significantly in number, structure and distribution throughout a sunspot cycle.

Estimates of their number, along with descriptions of the shapes, position angles and extents of the more prominent streamers, might be undertaken.

Close to the sun's poles (like the earth's north and south poles), we can see special sun rays streaming out on the poles' magnetic lines of force. The width of these streamers are only a few hundred kilometers.  Refer to Figure 5.9 for isolated streamer.

         

the extent of the streamers is almost the same in both images
