Integration of solar flare and coronal mass ejection event dataHarvard Dataverse [PDF]

Data in Brief
Solar flares and coronal mass ejections are solar transient events that can impact our technological infrastructure in near-Earth and Earth environments. While related, not all flares generate CMEs and there are a limited number of resources that connect

Association Between Geomagnetic Activity and Unsuccessful Out-of-Hospital Cardiac Arrest. [PDF]

Geohealth
Abstract Out‐of‐hospital cardiac arrests (OHCAs) represent a significant global health challenge, with a survival rate <10%. Recent research has demonstrated that geomagnetic activity (GMA) can disrupt the circadian rhythm. Therefore, GMA may affect patient outcomes after an OHCA event wherein resuscitation is attempted.

Review of Fast Solar Jets and Coronal Mass Ejections [PDF]

Iranian Journal of Astronomy and Astrophysics, 2023
The Sun is a magnetically active star. It has a powerful magnetic field that shifts slightly from year to year until it reverses about every eleven years. The sun's magnetic field has many effects, the collection of which is called solar activity such as,

What Do Halo CMEs Tell Us about Solar Cycle 25?

The Astrophysical Journal Letters, 2023
It is known that the weak state of the heliosphere due to diminished solar activity in cycle 24 backreacted on coronal mass ejections (CMEs) to make them appear wider for a given speed. One of the consequences of the weak state of the heliosphere is that

Improving the Arrival Time Estimates of Coronal Mass Ejections by Using Magnetohydrodynamic Ensemble Modeling, Heliospheric Imager Data, and Machine Learning

The Astrophysical Journal, 2023
The arrival time prediction of coronal mass ejections (CMEs) is an area of active research. Many methods with varying levels of complexity have been developed to predict CME arrival.

Deflection of Coronal Mass Ejections in Unipolar Ambient Magnetic Fields

The Astrophysical Journal, 2023
The trajectories of coronal mass ejections (CMEs) are often seen to deviate substantially from a purely radial propagation direction. Such deviations occur predominantly in the corona and have been attributed to “channeling” or deflection of the eruptive

Evolution of the Radial Size and Expansion of Coronal Mass Ejections Investigated by Combining Remote and In Situ Observations

The Astrophysical Journal, 2023
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 strength as the CME propagates.

A Comparative Study of Two Contrasting Cosmic-Ray Events Caused by Solar Eruptions from NOAA AR 12673 in 2017 September

The Astrophysical Journal, 2023
Two major solar eruptions on AR 12673 produced a Forbush decrease (FD) event (reduction of cosmic rays) on 2017 September 8 and ground-level enhancement (GLE; enhancement of cosmic rays) on 2017 September 10.
