Abstract
It is of great interest and importance to study the variabilities of solar spectral irradiance (SSI) in heliophysics, in Earth’s climate, and space weather applications. We will discuss the results of the solar variability observed in EUV, UV (LYRA) & X-ray (GOES) using the spatially resolved and segmented full-disk images of the Sun (obtained from PROBA2/SWAP, SDO/AIA & Hinode/XRT) in relation to the underlying photospheric magnetic fields, measured from SDO/HMI.
When: September 27, 2PM
Where: Meridian room at the ROB and on Webex
