We have the pleasure of announcing the next instalment of the UK-SOSS which will take place at 10:00 (UK time) on 24th of June.

Speaker: Prof. Lucie Green (UCL, Mullard Space Science Laboratory)
Title: What can magnetic helicity tell us about the likelihood of an eruption from active regions?Zoom link: https://zoom.us/j/95338171418
Meeting ID 953 3817 1418

Abstract:

Understanding the physical processes that underly the occurrence of coronal mass ejections is a key area of research, whilst being able to forecast an ejection beforehand would provide significant benefits to space weather forecasting lead-times. In this talk, these two aims will be discussed in the context of a quantity known as magnetic helicity, in particular the so-called helicity proxy that can be determined from modelled active region magnetic field and which has shown potential in being able to indicate when an active region will produce eruptive activity. Results will be presented for NOAA active region 11158, that builds on the helicity proxy analysis already presented by Thalmann et al. (2019) to incorporate the observed evolution of the coronal field and the physical processes taking place in the time leading up to an eruption.

We look forward to welcoming you all to the talk at that time.
With warmest regards,
Marianna Korsos, Chris Nelson, and Jiajia Liu
