This plasma cloud, though, missed the Earth and so did not cause auroras. The explosion created Coronal Mass Ejections which dispersed high energy plasma into the Solar System. The image sequence was taken by the Earth-orbiting Solar Dynamics Observatory (SDO) in one color of ultraviolet light specifically emitted by helium, and another color of X-ray light specifically emitted by iron. The filament had been seen hovering over the Sun's surface for over a week before it erupted earlier this month.

More details regarding how to join the meeting will follow shortly. The meeting will consist of both invited and contributed talks along with poster contributions. This meeting will be hybrid if enough in-person attendees register in advance, otherwise this meeting will take place online only. What magnetic field parameters would be useful for the next generation of space weather models to predict solar energetic particles and their associated flares and coronal mass ejections? What effect do the solar and heliospheric magnetic fields have on the acceleration, injection and propagation of energetic particles? The timing of this meeting is particularly appropriate given the ongoing SWARM project and the availability of data from new missions such as Parker Solar Probe and Solar Orbiter. In this meeting we aim to discuss the configuration and evolution of the solar magnetic field in the build-up to solar eruptive events as well as the production and propagation of solar energetic particles.

This is one of the aims of NERC’s “SWIMMR Aviation Risk Monitoring” (SWARM) project. One of the main issues is what input parameters, in particular magnetic field properties of source regions taken from solar observations, are required to improve forecasts provided by data-driven models. Achieving this task is very difficult because it requires a multidisciplinary approach combining a broad range of remote and in-situ observations, data-driven modelling and simulations. To mitigate the risk posed by SEPs and solar eruptive events we must be able to forecast these events prior to their occurrence. Large gradual SEP events, associated with high-energy protons (up to tens of GeV), can cause hazardous space weather conditions at Earth and hence pose a severe radiation risk for crewed spaceflight and a significant threat to near-Earth technological assets. Solar energetic particles (SEPs) are accelerated by magnetic reconnection-driven processes during solar flares and by CME-driven shocks.
