Multi-Thermal CME Detection with ALMANAC
Thomas Williams, Christopher B. Prior, David MacTaggart +1
Reliable identification of low-coronal CME origins remains a key limitation in space weather forecasting with coronagraphs not directly resolving low-coronal signatures. We present…
Investigating the Efficacy of Topologically Derived Time Series for Flare Forecasting. II. XGBoost Model
Thomas Williams, Christopher B. Prior, David MacTaggart +1
Solar flares are a primary driver of space weather, and forecasting their occurrence remains a significant challenge. This paper presents a novel flare prediction model based on to…
Investigating the Effects of Atmospheric Stratification on Coronal Active Region Field Modelling
Oliver Rice, Christopher Prior
Understanding the evolution of the complex magnetic fields found in solar active regions is an active area of research. There are numerous models for such fields which range in the…
Investigating the Efficacy of Topologically Derived Time-Series for Flare Forecasting. I. Dataset Preparation
Thomas Williams, Christopher B. Prior, David MacTaggart
The accurate forecasting of solar flares is considered a key goal within the solar physics and space weather communities. There is significant potential for flare prediction to be…
Deciphering Pre-solar-storm Features Of September-2017 Storm From Global And Local Dynamics
Breno Raphaldini, Mausumi Dikpati, Aimee A. Norton +4
We investigate whether global toroid patterns and the local magnetic field topology of solar active region AR12673 together can hindcast occurrence of the biggest X-flare of solar…
Direct evidence: twisted flux tube emergence creates solar active regions
David MacTaggart, Chris Prior, Breno Raphaldini +2
The magnetic nature of the formation of solar active regions lies at the heart of understanding solar activity and, in particular, solar eruptions. A widespread model, used in many…
Magnetic winding -- a key to unlocking topological complexity in flux emergence
David MacTaggart, Chris Prior
Magnetic helicity is an invariant of ideal magnetohydrodynamics (MHD) that encodes information on the topology of magnetic field lines. It has long been appreciated that magnetic t…
Interpreting magnetic helicity flux in solar flux emergence
Chris Prior, David MacTaggart
Magnetic helicity flux gives information about the topology of a magnetic field passing through a boundary. In solar physics applications, this boundary is the photosphere and magn…
