Table 3. Solar minimum and maximum values compared to the intensity flux of medium solar activity cycle for X-ray, SXR, EUV, FUV and Lyman-alpha wavelength ranges.
Wavelength | High solar activity | Low solar activity |
|---|---|---|
X-ray [1–20 Å ] | −2.6 | −0.4 |
SXR [20–100 Å ] | −1.8 | −0.7 |
EUV [100–912 Å] | −1.5 | −0.8 |
FUV [912–1180 Å ] | −1.3 | −0.8 |
Lyman-α [1200–1300 Å] | −1.3 | −0.9 |
