Low-frequency radio astronomy instruments are severely impacted by our Earth’s ionosphere; depending on the conditions, one may observe bulk displacements in source positions, or even scintillation. Moving into the SKA-Low era, it is important to use our current capabilities to understand the ionosphere, as things become more complicated with very long baselines. Fortunately, modern instruments, such as LOFAR and the MWA, are well-suited to further our understanding of the Earth’s ionosphere. A prominent example of our being able to identify ionospheric activity are the tubular structures reported by Cleo Loi. The Real-Time System (RTS) is one of a few existing calibration pipelines designed for processing MWA data. One aspect of this calibration is to determine ionospheric effects; using this calibration scheme, we are able to observe the ionosphere at a high-resolution (spatial and temporal). Following on from these results, we have developed software to analyse ionospheric activity. In this talk, I will discuss our characterisation of the ionosphere derived from datasets collected for the Epoch of Reionisation (EoR) project. With our large sample of data, we observe a wide range of ionospheric activities, and present a metric describing the quality of radio data due to the ionosphere. We also detail a novel method to reconstruct a scalar field representing the total electron content of the ionosphere, temporal correlations, and a possible connection to K_p indices recorded from geomagnetic observatories around the world.
