S3-0X (new team!): Flare Precursors (Lead: Larisza Krista)

  • DEFT flare forecasting based on GOES/SUVI EUV precursor signatures – signals are consistent across all magnitudes. 10% false detection rate. Major challenge: distinguishing detections for small and large flares.
  • Future effort: lower false positive and negative detections, run on blind data and no-flare data. Incorporate other wavelengths to improve tool. Tailor method to different industry needs (time window).
  • New team member: Juliana Vievering (John Hopkins APL).

S3-04: Radio Observations of the Sun and Heliopshere (Lead: Pietro Zucca)

  • Solar radio imaging using LOFAR. Calibrated images to study the position and the fine structures of solar radio bursts. This radio information is used in the context of multiwavelength observation from ground- and space-based observatories.
  • Goal: operating a dedicated LOFAR station for space weather purposes (IDOLS - Incremental development of LOFAR Space-weather). Calibrated real-time solar radio bursts and ionospheric scintillation is obtained.Future work will involve adding more stations to IDOLS including coordinated observations with International LOFAR stations. Tools to forecast SEP using radio information.

S3 Cluster Paper – Manolis Georgoulis

  • S3 Cluster paper submitted on the prediction of solar eruptive events (flares, CMEs and SEP events). The paper summarizes progress achieved since the landmark COSPAR / ILWS roadmap paper of Schrijver et al. (2015) and provides recommendations for the short- (<  5 years) and long-term (10+ years) future.  
  • Once published, we look forward to assessing the impact of the paper in the community. We would like to see efforts toward unifying infrastructures for prediction as discussed in the paper. Will also advertise the paper during the 2024 COSPAR General Assembly.
