Machine Learning Models for Solar Energetic Particle Prediction (Dr. Spyros Kasapis, Department of Astrophysical Sciences, Princeton University, USA )	20 August 2026 (Zoom seminar)	20 August 2026	Подробнее	Solar energetic particle (SEP) events have attracted increasing attention because of the significant radiation hazards they pose to aviation, spacecraft electronics, and human missions beyond Earth’s magnetosphere. From a scientific standpoint, SEP events are of particular interest because they result from a chain of physical processes spanning the solar surface, corona, and heliosphere, providing valuable insight into particle acceleration and transport mechanisms that are relevant throughout astrophysics. Improving our ability to understand and predict SEP events is therefore important both for advancing fundamental scientific knowledge and for protecting space-based technologies and exploration activities. Traditionally, SEP forecasting has relied on physics-based models and empirical approaches. More recently, machine learning (ML) has emerged as a powerful complementary tool for understanding and predicting SEP events. This presentation reviews the current landscape of ML-based SEP prediction models, examines the datasets used for their development, compares their architectures, inputs, and outputs, and, based on these findings, proposes best practices and recommendations for future research.
Solar Wind Pressure Pulses and the Magnetosphere-Ionosphere System (Dr. David G. Sibeck, Sciences and Exploration Directorate, Goddard Space Flight Center, USA)	3 September 2026 (Zoom seminar)	3 September 2026	Подробнее	Magnetic reconnection and the response to solar wind dynamic pressure pulses represent two fundamentally different but potentially closely interlinked modes of solar wind-magnetosphere interaction that have received order of magnitude different levels of attention (35000 to 45000 papers for magnetospheric magnetic reconnection versus 3800 for magnetospheric pressure pulses according to Google Scholar). While acknowledging the importance of the former mode, this presentation addresses the latter. It begins by demonstrating how kinetic processes transform weak (~10%) density and dynamic pressure variations associated with many solar wind rotational and tangential discontinuities into factor of 2-3 variations within the foreshock immediately upstream from the dayside bow shock. It then addresses the transmission of these very strong upstream pressure variations across the bow shock, which often results in large amplitude sunward or antisunward flows in both the inner AND outer magnetosheath. Repetitive density/pressure pulses with durations of 1-5 minutes seen by spacecraft in the foreshock AND the magnetosheath drive riplets on the magnetopause that other spacecraft within the magnetosphere detect on the basis of bipolar magnetic field and plasma flow components normal to the nominal magnetopause, magnetic field strength enhancements, and plasma flows perpendicular to riplet wavefronts, not only in the magnetosphere but also in the magnetosheath. The riplets should sweep across the dayside magnetopause in a direction determined by the (typically but not always antisunward and dawnward) normal to the driving solar wind discontinuity, sometimes necessitating sunward motion against the magnetosheath flow. Passage of the riplets can initiate magnetopause reconnection or simply cause transient encounters with any preexisting low latitude boundary layer exhibiting reconnection signatures, such as particle distributions and accelerated flows indicating open magnetic field lines. The riplets transmit fast mode waves into the magnetosphere readily detected at geosynchronous orbit and by magnetometers under the equatorial electrojet. They transmit intermediate mode waves that carry currents along magnetic field lines down into the high-latitude ionosphere, which produce traveling convection vortex signatures in ground magnetograms.
9^th Asia-Oceania Space Weather Alliance Workshop	November 08 — 11, 2026 Tainan, Taiwan	Abstract Submission Deadline: August 30	Подробнее	AOSWA (Asia Oceania Space Weather Alliance) was established in 2010 and dedicated to fostering international cooperation in regional observations, research, and operational products. Given the global connectivity of space weather, it is essential for the Asia-Pacific region spanning the geomagnetic equator to strengthen regional collaboration against unique ionospheric disturbances. We hope the AOSWA framework will help us improve space weather activities since Asia-Oceania has become one of the most important regions for space utilities and requires close communication and cooperation. This year, AOSWA in collaboration with the Central Weather Administration and Taiwan Space agency, will host the 9th AOSWA workshop (AOSWA 2026) from November 8 to 11, 2026 in Tainan, Taiwan. The purpose of this workshop is to promote regional and global collaboration and information sharing on space weather observation, research, and operations. It aims to bring together not only members of the Asia-Oceania scientific community but also representatives from other international organizations involved in space weather. We believe this workshop will provide a valuable opportunity to discuss and share recent achievements on space weather observation, research, forecasting, and applications, paving the way for stronger future collaboration across Asia, Oceania, and the international space weather communities.
