On modelling the 2017 galactic cosmic ray depression
O. P. M. Aslam, D. MacTaggart, M. S. Potgieter +2
In the second half of 2017, as Solar Cycle 24 approached its minimum, a pronounced and rigidity-dependent depression in the galactic cosmic ray (GCR) proton flux was observed using…
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…
On field line slippage rates in the solar corona
David MacTaggart
Magnetic reconnection is one of the fundamental dynamical processes in the solar corona. The method of studying reconnection in active region-scale magnetic fields generally depend…
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…
The magnetic topology of AR13664 leading to its first halo CME
David MacTaggart, Tom Williams, OPM Aslam
In the first half of May 2024, the solar active region (AR)13664 was responsible for generating the strongest geomagnetic storm in over 20 years, through an enhanced production of…
Photospheric signatures of CME onset
Aslam Ottupara, David MacTaggart, Tom Williams +2
Coronal mass ejections (CMEs) are solar eruptions that involve large-scale changes to the magnetic topology of an active region. There exists a range of models for CME onset which…
On turbulent magnetic reconnection: fast and slow mean steady-states
Sage Stanish, David MacTaggart
We investigate a model of turbulent magnetic reconnection introduced by Higashimori, Yokoi and Hoshino (Phys. Rev. Lett. 110, 255001) and show that the classic two-dimensional, ste…
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…
