Solar Flare Observations and Model Predictions - March 24, 2023

Explore solar flare physics and space weather predictions in this comprehensive lecture from the Simons Foundation. Delve into the onset of Sunspot Cycle 25 and examine varying predictions about upcoming space weather intensity. Learn about recent discoveries from Cycle 24 through UV spectra analysis using the Interface Region Imaging Spectrograph (IRIS), particularly focusing on chromospheric emission line characteristics. Discover how the Daniel K. Inouye Solar Telescope (DKIST) will revolutionize solar flare observation through unprecedented spatial, temporal, and spectral resolution capabilities. Examine time-dependent model predictions for hydrogen line broadening in optical spectra of solar flares, and understand how DKIST's advanced capabilities can validate these models while providing crucial insights for interpreting stellar flare spectra. Gain valuable knowledge about the intersection of observational data and theoretical models in solar physics, and understand their implications for space weather forecasting.
