Relationship of the nightglow 630.0nm emission intensity to the solar extreme ultraviolet

Journal of Atmospheric and Solar-Terrestrial Physics, 2013
Abstract It is well known that the 630.0 nm nightglow emission intensity at mid latitudes increased more than twofold in periods of maximum sunspot activity. It is assumed that this phenomenon is caused by variations in solar ultraviolet radiation intensity in solar activity cycles ( Fishkova, 1983 ).

On the Failure of Standard Emission Measure Analysis for Solar Extreme-Ultraviolet and Ultraviolet Irradiance Spectra

Astrophysical Journal, 1995
We perform emission measure analysis of new and accurate UV (λ > 1200 A) and extreme-ultraviolet (EUV) (λ ≤ 1200 A) irradiance ("Sun-as-a-star") emission-line spectra of the Sun. Our data consist of (1) daily averaged UV irradiances from the SOLSTICE on the UARS spacecraft and (2) EUV irradiances obtained on the same date from a m spectrograph flown on

Extreme Ultraviolet Emission Lines of ca xv in Solar and Laboratory Spectra

Solar Physics, 2003
New R-matrix calculations of electron impact excitation rates in Ca xv are used to derive theoretical electron density diagnostic emission line intensity ratios involving 2s22p2–2s2p3 transitions, specifically R1=I(208.70 A)/I(200.98 A), R2=I(181.91 A)/I(200.98 A), and R3=I(215.38 A)/I(200.98 A), for a range of electron temperatures (Te=106.4–106.8 K ...

Direct measurements of the gradual extreme ultraviolet emission from large solar flares

Solar Physics, 1983
Broadband sensors aboard the Naval Research Laboratory's SOLRAD 11 satellites measured solar emission in the 0.5 to 3 A, 1 to 8 A, 8 to 20 A, 100 to 500 A, 500 to 800 A, and 700 to 1030 A bands. Data from sixteen large flares show that the EUV emission is dominated by gradual emission which parallels the soft X-ray emission in duration and magnitude ...
