SDO GAIA-DEM
GAIA-DEM GAIA-DEM is a database of Differential Emission Measure (DEM) maps. The DEM is a measure of the thermal structure of the coronal plasma, representing the quantity... -
Astronomical Calendar: Sun and Moon Ephemerides and Twilight Calculator
The Astronomical Calendar is a software package for automated calculations of the celestial coordinates (ephemerides) of the Sun and Moon. It computes the times of sunrise and... -
Nancay Decameter Array observation database
Decametric radio observation from Nancay decameter array. The Nancay Decameter Array (NDA) at the Station de Radioastronomie de Nancay (SRN) is a phased array of 144 "Teepee"... -

USET sunspot drawing The Uccle Solar Equatorial Table (USET) facility at the Royal Observatory of Belgium has gathered an uninterrupted series of sunspot drawings since year... -
Abundances in solar atmosphere
An analysis of the chemical composition of the solar atmosphere is performed using spectrograms of the daylight sky obtained on the ZTS telescope (dispersion 3{AA}/mm,... -
EUV spectrum of solar active region
We present wavelengths and absolute intensities for 269 emission lines from a single active region observed by the Solar EUV Rocket Telescope and Spectrograph (SERTS) on 1989... -
In the Trenches of the solar-stellar connection. VII.
The Wilson-Bappu effect (WBE) is a remarkable correlation between the width of the chromospheric emission core of the CaII 3934{AA} K line and stellar absolute visual magnitude... -
The Fermi-LAT long-term transient sources (1FLT)
We present the first Fermi Large Area Telescope (LAT) catalog of long-term {gamma}-ray transient sources (1FLT). This comprises sources that were detected on monthly time... -
Solar flare variability from GOES-15 Ly{alpha} obs.
The Lyman-alpha (Ly{alpha}) line of neutral hydrogen at 121.6nm is by far the brightest emission line in the vacuum ultraviolet spectral range of the Sun. The emission at this... -
Vanadium log(gf) and transition probabilities
New emission branching fraction measurements for 836 lines of the first spectrum of vanadium (VI) are determined from hollow cathode lamp spectra recorded with the National... -
UV spectrum of the quiet Sun above the limb
We investigate the absolute calibration of the EUV Imaging Spectrometer (EIS) on Hinode by comparing EIS full-disk mosaics with irradiance observations from the EUV Variability... -
Solar photoionization rates
Extreme UV (EUV) spectra from the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED)/Solar EUV Experiment are used to infer photoionization rates in the inner... -
Sun and HD 84937 TiII log(gf) and abundances
Atomic transition probability measurements for 364 lines of Ti II in the UV through near-IR are reported. Branching fractions from data recorded using a Fourier transform... -
Rare earth abundances
We have derived new abundances of the rare earth elements Pr, Dy, Tm, Yb, and Lu for the solar photosphere and for five very metal-poor, neutron-capture r-process-rich giant... -
Solar flux model in 30-1300nm wavelength range
Solar photon scattering probabilities (g values) have been calculated for discrete transitions in 12 species, in a format designed primarily to allow analysis of spacecraft... -
Models of solar magnetic structures
This paper presents semiempirical models of various solar magnetic structures, extending from the photosphere to the chromosphere. The models have been derived from non-LTE...
