The Solar Chromosphere
The
chromosphere of the Sun is a thin transitional layer between the
photosphere and the corona.
It's thickness is about 8000 km (5000 miles) and is comparable to the
shell of an egg. Spicules, or
small jets of hydrogen gas, will go up a little higher on occasion.
The chromosphere is responsible
for several of the most fascinating aspects of the sun. Towering
prominences
explode out into space. Colossal
filaments flow across it like rivers of
hot lava and Earth sized (or larger)
active regions move across the disk.
In the image above, the
orange portion of the chromosphere was photographed at the
Hydrogen-Alpha (Ha) emission line (6563A) and the violet area comes
from the Calcium K line (CaK, 3933A).
The yellow section is a white
light image from the entire solar spectrum.
