WebFeb 23, 2024 · The chromosphere lies between the photosphere, or bright surface of the Sun that emits visible light, and the super-heated corona, or outer atmosphere of the Sun at the source of solar eruptions. The chromosphere is a key link between these two regions and a missing variable determining the Sun’s magnetic structure. WebThe chromosphere represents the dynamic transition between the cool temperature minimum of the outer photosphere and the diffuse million-degree corona above. It derives its name and pink colour from the red …
Websize in the raster scan, and the sampling along the slit were set to 0″.16. Each raster scan consisted of 250 steps. The observed field of view is 40″ by 40″. The observations were done with the 308 subaperture adaptive optics. The spatial resolution of imaging on this day is estimated at twice the step size, which is 0″.32. WebObservations made during eclipses show that the chromosphere is about 2000 to 3000 kilometers thick, and its spectrum consists of bright emission lines, indicating that this layer is composed of hot gases emitting light at discrete wavelengths.
WebJun 8, 2024 · The chromosphere is best imaged in the H-alpha emission wavelength. The challenge is that the underlying photosphere completely overpowers the signal from the chromosphere. The solution is to image as precise as possible in the H-alpha wavelength. The concept is similar to using narrowband filters when the full moon is out. WebObservations made during eclipses show that the chromosphere is about 2000 to 3000 kilometers thick, and its spectrum consists of bright emission lines, indicating that this …
