73P/Schwassmann-Wachmann 3 is a short-period comet that has undergone multiple fragmentation events in the last few decades. During May-June 2006, while passing near Earth, multipl…
Observational Constraints on the Radial Evolution of O Temperature and Differential Flow in the Inner Heliosphere
Yeimy J. Rivera, Kristopher G. Klein, Joseph H. Wang +15

Evolution of the Radial Size and Expansion of Coronal Mass Ejections Investigated by Combining Remote and In-Situ Observations
Bin Zhuang, Noé Lugaz, Nada Al-Haddad +4
A fundamental property of coronal mass ejections (CMEs) is their radial expansion, which determines the increase in the CME radial size and the decrease in the CME magnetic field s…

We present an analysis of {\it in situ} and remote-sensing measurements of a coronal mass ejection (CME) that erupted on 2021 February 20 and impacted both the Solar TErrestrial RE…
CMEs and SEPs During November-December 2020: A Challenge for Real-Time Space Weather Forecasting
Erika Palmerio, Christina O. Lee, M. Leila Mays +20
Predictions of coronal mass ejections (CMEs) and solar energetic particles (SEPs) are a central issue in space weather forecasting. In recent years, interest in space weather predi…

We present the first statistical analysis of complexity changes affecting the magnetic structure of interplanetary coronal mass ejections (ICMEs), with the aim of answering the que…
Investigating The Cross-section of Coronal Mass Ejections Through the Study of Non-Radial Flows with STEREO/PLASTIC
N. Al-Haddad, A. B. Galvin, N. Lugaz +2
The solar wind, when measured close to 1 au, is found to flow mostly radially outward. There are, however, periods when the flow makes angles up to 15 away from the radial…
