| Wavelength: 5000 Angstroms | Width: Broad |
| Filter: White Light | Temperature: 4,000-6,400 Kelvin |
| This filter images the photosphere of the Sun. It includes the wave bands that we can see in, ie normal light. The image shows a sunspot which occured on 18th June 1998. |
 |
| Wavelength: 1700 Angstroms | Width: 200 Angstroms |
| Filter: Broad | Temperature: 4,000-10,000 Kelvin |
| This filter images the chromosphere in ultraviolet light. This is region of the solar atmosphere which is the coolest, it is also the lowest level of the atmosphere. |
 |
| Wavelength: 1600 Angstroms | Width: 275 Angstroms |
| Filter: CI, FeII | Temperature: 4,000-10,000 Kelvin |
| This filter images the chromosphere in ultraviolet light. This is region of the solar atmosphere which is the coolest, it is also the lowest level of the atmosphere. |
 |
| Wavelength: 1550 Angstroms | Width: 20 Angstroms |
| Filter: CIV | Temperature: 60,000-250,000 Kelvin |
| This filter images the transition region. The image above was taken at the same time as the sunspot in the white light image, the activity around the sunspot can be seen. |
 |
| Wavelength: 1216 Angstroms | Width: 84 Angstroms |
| Filter: HI Lyman Alpha | Temperature: 10,000-30,000 Kelvin |
| This filter images the upper part of the chromosphere. The image was taken at the same time as the sunspot in the white light image, the activity around the sunspot can be seen. |
 |
| Wavelength: 171 Angstroms | Width: 6.4 Angstroms |
| Filter: FeIX | Temperature: 160,000-2,000,000 Kelvin |
| This filter is the first of the extreme ultraviolet light (EUV) bands. it images the corona, and low underlying plasma structures can be seen. |
 |
| Wavelength: 195 Angstroms | Width: 6.5 Angstroms |
| Filter: FeXII | Temperature: 500,000-2,000,400 Kelvin |
| This filter images the corona in an extreme ultraviolet light (EUV) band. This is one of the more commonly used filters and can see a good range of plasma structures in the corona. |
 |
| Wavelength: 284 Angstroms | Width: 10.7 Angstroms |
| Filter: FeXV | Temperature: 1,250,000-4,000,000 Kelvin |
| This filter images the corona in an extreme ultraviolet light (EUV) band. This band picks out the hottest coronal structures and can resolve features that the other EUV bands (171, 185 Angstroms) can only see as a hot blur. |
