Description
Harry Greatorex, Ryan Milligan and Ingolf Dammasch compare how different instruments measure the same solar flares in this 2024 Europe PMC paper. Their focus is Lyman-alpha emission, which carries much of a flare's energy but was rarely observed until recent years. Several spacecraft now record it, though not in the same way.
They studied three mid-sized flares, each seen by one of the GOES instruments plus at least one other observatory. Basic relative flux agreed fairly well across instruments. But contrast, excess flux, total energy and timing could differ a lot, in some cases by a factor of five. The authors offer the findings as a guide for multi-instrument flare studies.
