Understanding the Complex Morphology of a Coronal Mass Ejection. III: How to Create a Severe Geomagnetic Storm
Cecilia Mac Cormack, Abril Sahade, Erika Palmerio +4
On April 21, 2023, a complex filament eruption produced an Earth-directed coronal mass ejection (CME) that triggered the first severe geomagnetic storm of solar cycle 25. The prima…
The First Quantitative Study of Tail Regrowth of CME-Driven Disconnection in Comet C/2023 P1 Nishimura
Shaheda Begum Shaik, Guillermo Stenborg, Phillip Hess +3
Comet C/2023 P1 (Nishimura) was observed by the Solar Orbiter Heliospheric Imager (SoloHI), onboard the Solar Orbiter spacecraft, from 2023 September 1 to 14. During this period, t…
Polarimeter to Unify the Corona and Heliosphere (PUNCH)
Craig E. DeForest, Sarah E. Gibson, Ronnie Killough +74
The Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission is a NASA Small Explorer to determine the cross-scale processes that unify the solar corona and heliosphere. PUN…
Prominence material observed by SoloHI beyond 0.5au
C. Mac Cormack, S. B. Shaik, P. Hess +2
With the combination of observations from in-situ and high-resolution remote sensing instruments, the Solar Orbiter (SolO) mission has become a particularly valuable mission for st…
Understanding the complex morphology of a CME: multi-view analysis and numerical modeling
Cecilia Mac Cormack, Abril Sahade, Angelos Vourlidas +3
Although all coronal mass ejections (CMEs) that propagate into the heliosphere should contain a magnetic flux rope (MFR) component, the majority do not exhibit the expected white-l…
A Multi-viewpoint CME Catalog Based on SoloHI Observed Events
C. Mac Cormack, S. B. Shaik, P. Hess +2
Coronal Mass Ejections (CMEs) are significant drivers of geomagnetic activity, and understanding these structures is critical to developing and improving forecasting tools for spac…
A Study on the Nested Rings CME Structure Observed by the WISPR Imager Onboard Parker Solar Probe
Shaheda Begum Shaik, Mark G. Linton, Sarah E. Gibson +5
Despite the significance of coronal mass ejections (CMEs) in space weather, a comprehensive understanding of their interior morphology remains a scientific challenge, particularly…
The Sun's Alfven Surface: Recent Insights and Prospects for the Polarimeter to Unify the Corona and Heliosphere (PUNCH)
Steven R. Cranmer, Rohit Chhiber, Chris R. Gilly +7
The solar wind is the extension of the Sun's hot and ionized corona, and it exists in a state of continuous expansion into interplanetary space. The radial distance at which the wi…
A Coronal Mass Ejection followed by a prominence eruption and a plasma blob as observed by Solar Orbiter
A. Bemporad, V. Andretta, R. Susino +26
On February 12, 2021 two subsequent eruptions occurred above the West limb, as seen along the Sun-Earth line. The first event was a typical slow Coronal Mass Ejection (CME), follow…
SunCET: A compact EUV instrument to fill a critical observational gap
James Paul Mason, Phillip C. Chamberlin, Daniel Seaton +16
The Sun Coronal Ejection Tracker (SunCET) is an extreme ultraviolet imager and spectrograph instrument concept for tracking coronal mass ejections through the region where they exp…
WISPR Imaging of a Pristine CME
Phillip Hess, Alexis Rouillard, Athanasios Kouloumvakos +6
The Wide-field Imager for Solar Probe (WISPR) on board the Parker Solar Probe (PSP) observed a CME on 2018 November 01, the first day of the initial PSP encounter. The speed of the…
Relationship of EUV Irradiance Coronal Dimming Slope and Depth to Coronal Mass Ejection Speed and Mass
James Paul Mason, Thomas N. Woods, David F. Webb +3
Extreme ultraviolet (EUV) coronal dimmings are often observed in response to solar eruptive events. These phenomena can be generated via several different physical processes. For s…
Propagation of the 7 January 2014 CME and Resulting Geomagnetic Non-Event
M. L. Mays, B. J. Thompson, L. K. Jian +8
On 7 January 2014 an X1.2 flare and CME with a radial speed 2500 km s was observed from near an active region close to disk center. This led many forecasters to est…
CME propagation: Where does solar wind drag take over?
Nishtha Sachdeva, Prasad Subramanian, Robin Colaninno +1
We investigate the Sun-Earth dynamics of a set of eight well observed solar coronal mass ejections (CMEs) using data from the STEREO spacecraft. We seek to quantify the extent to w…
Strong coronal channelling and interplanetary evolution of a solar storm up to Earth and Mars
Christian Möstl, Tanja Rollett, Rudy A. Frahm +15
The severe geomagnetic effects of solar storms or coronal mass ejections (CMEs) are to a large degree determined by their propagation direction with respect to Earth. There is a la…
Connecting speeds, directions and arrival times of 22 coronal mass ejections from the Sun to 1 AU
C. Möstl, K. Amla, J. R. Hall +15
Forecasting the in situ properties of coronal mass ejections (CMEs) from remote images is expected to strongly enhance predictions of space weather, and is of general interest for…
