| The clouds will just impede your direct view and the light of corona, chromosphere, and prominences may trickle through. |
|
| For decades astronomers labored to get good photographs of the chromosphere, and in particular its spectrum. |
|
| But the hotter hydrogen in the chromosphere and corona above it is madly emitting at the same wavelength. |
|
| Prominences, flares, plages, and other features of the solar chromosphere can be observed in hydrogen light. |
|
| The chromosphere is the first layer of atmosphere above the sun's surface layer. |
|
| Solar flares appear as sudden, intense flashes in the chromosphere of the Sun. |
|
| Because it strongly emits the high-excitation lines of helium, the chromosphere was originally thought to be hot. |
|
| The chromosphere looks like a reddish rim and is caused by hot hydrogen atoms that surround the Sun. |
|
| Solar prominence, dense cloud of incandescent ionized gas projecting from the Sun's chromosphere into the corona. |
|
| The chromosphere is seen only during solar eclipses when the Moon passes in front of the Sun. |
|
| During a solar eruption, a huge amount of energy that the Sun is in the chromosphere and the crown is issued instantly. |
|
| The solar atmosphere is composed of three main layers: the chromosphere, the transition zone and the corona. |
|
| The most prominent structures in the chromosphere, especially in the limb, are the clusters of jets, or streams, of plasma called spicules. |
|
| Above the photosphere is the chromosphere, which can be compared to the Earth's upper atmosphere. |
|
| Like the chromosphere, the corona can only be seen by eye during a total eclipse, although there are other technical ways to observe it between times. |
|
| The reddish prominences and chromosphere of the Sun, around the Moon's limb, can now be seen. |
|
| Because this line is so strong, it is the best means for studying the chromosphere. |
|
| The extensions of faculae up into the chromosphere become visible over the entire disk in spectroheliograms taken at the wavelengths of hydrogen or ionized calcium vapour. |
|
| Energetic particles impinging from the corona into the chromosphere are known to drive strong, downward-propagating shocks in active region chromospheres during the impulsive phases of flares. |
|
| The rules for this interplay are simple: every point in the chromosphere where the magnetic field is strong and vertical is hot and hence bright, and every place where it is horizontal is dark. |
|
|
|
| We will center our attention on the flare chromosphere, from which most of the radiation originates. |
|
| During totality, the chromosphere and corona come into view, and the Sun can be viewed without filters. |
|
| The Sun's thin, pinkish inner atmosphere, or chromosphere, is visible only during a total solar eclipse. |
|
| The various manifestations of solar activity are driven by the total amount of magnetic flux emerging through the photosphere into the chromosphere and corona, and its temporal and spatial distribution. |
|
| Spicule, a jet of dense gas ejected from the Sun's chromosphere. |
|
| This review focuses on dynamics of the solar chromosphere, which serves as a good proxy for understanding processes in stellar chromospheres as well. |
|
| Above this layer is a thin region known as the chromosphere. |
|
| Importantly, since excited orthohelium cannot fully relax back to the ground state, it remains available to recondense with atomic hydrogen in the chromosphere. |
