Solar-cycle irradiance variations over the last four billion years
Anna V. Shapiro, Alexander I. Shapiro, Laurent Gizon +2
The variability of the spectral solar irradiance (SSI) over the course of the 11-year solar cycle is one of the manifestations of solar magnetic activity. There is a strong evidenc…
High solar cycle spectral variations inconsistent with stratospheric ozone observations
W. T. Ball, J. D. Haigh, E. V. Rozanov +5
Some of the natural variability in climate is understood to come from changes in the Sun. A key route whereby the Sun may influence surface climate is initiated in the tropical str…
Detection of Solar Rotational Variability in the LYRA 190 - 222 nm Spectral Band
A. V. Shapiro, A. I. Shapiro, M. Dominique +4
We analyze the variability of the spectral solar irradiance during the period from 7 January, 2010 until 20 January, 2010 as measured by the Herzberg channel (190-222 nm) of the La…
Eclipses observed by LYRA - a sensitive tool to test the models for the solar irradiance
A. I. Shapiro, W. Schmutz, M. Dominique +1
We analyze the light curves of the recent solar eclipses measured by the Herzberg channel (200-220 nm) of the Large Yield RAdiometer (LYRA) onboard PROBA-2. The measurements allow…
Color Variability of the Blazar AO 0235+16
V. A. Hagen-Thorn, V. M. Larionov, C. M. Raiteri +5
Multicolor (UBVRIJHK) observations of the blazar AO 0235+16 are analyzed. The light curves were compiled at the Turin Observatory from literature data and the results of observatio…
