Talk

Motions of sunspots cause the coronal magnetic field to become deformed with the effect that energy can be stored in the field. This energy can be released through events such as solar flares. Sunspots are known to rotate about their umbral centres, and this rotation contributes to the build-up of energy within an active region that can be released during an eruptive solar event. To understand...

Talk

The PUNCH (Polarimeter to UNify the Corona and Heliosphere) mission has three heliographic Wide-Field Imagers (WFIs) and one coronagraphic Narrow-Field Imager (NFI). Soon after launch, it was discovered that NFI has a very strong and unexpected dynamic stray light component. Driven by Earth-shine that has found a route through the optical system, this stray light is by far the dominant source...

Talk

Cumulative exposure to ionizing radiation at aviation altitudes poses significant health risks for aircrews and, at higher altitudes, astronauts. Physics-based models are commonly used to estimate radiation levels during flight; however, they often do not fully capture the rapidly varying and complex nature of atmospheric radiation, limiting real-time prediction accuracy.To address this...

15. Scientists need help selecting data-model comparison metrics: please embed this guidance in the analysis software

Talk

Comparing two number sets is a foundational component of the scientific process. We should not assume, however, that scientists know the best approach to conducting an appropriate data-model comparison for their particular need. There are many ways to compare two number sets, though, and it can be a confusing task to choose the right process for a particular situation. For example, certain...
