Title: Challenges in understanding the evolution of CMEs from corona to
heliosphere
Speaker:Anthea Coster of MIT Haystack Observatory.

Abstract:
Michael Buonsanto was an early leader in ionospheric storm studies. He
possessed a remarkable talent for synthesizing scientific insights from a
diverse array of measurements and instruments. His work rested on three key
pillars: scientific collaboration, innovative analysis techniques, and the
integration of observations with modeling and theory. He organized numerous
community workshops on this topic and published a seminal paper,
“Ionospheric Storms, A Review” (Buonsanto 1999). Michael’s pioneering
research was instrumental in identifying large mid-latitude electron
density gradients associated with ionospheric storms—a precursor to the
significant recognition of the space weather impacts associated with
ionospheric storms that occurred when the FAA’s WAAS system became
operational in 2003.

This lecture by Anthea Coster will explore the remarkable progress made
over the past 25 years in understanding ionospheric storms, driven by
advances in instrumentation, measurement methodologies, and ionospheric
modeling. It will highlight the growing importance of space weather
research and offer a reflective overview of developments in radio remote
sensing instrumentation and data analysis techniques, emphasizing the
enduring influence of Michael’s contributions. Finally, the lecture will
look ahead to the opportunities and challenges that await the next
generation of space weather research.
