On 10 September 2017, some of the strongest solar activity occurred in association with
active region 12673 (AR2673), including an X‐class solar flare and a fast coronal mass …

Observations of planetary auroras form a new area of planetary exploration from space,
especially for nonmagnetic planets since various kinds of auroras like Discrete, Proton and …

Abstract Between 4 and 10 September 2017, multiple solar eruptions occurred from active
region AR12673. NOAA's and NASA's well‐instrumented spacecraft observed the evolution …

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 …

Accurate forecasting of the properties of coronal mass ejections (CMEs) as they approach
Earth is now recognized as an important strategic objective for both NOAA and NASA. The …

An interval of exceptional solar activity was registered in early September 2017, late in the
decay phase of solar cycle 24, involving the complex Active Region 12673 as it rotated …

On 10 September 2017, solar energetic particles originating from the active region 12673
produced a ground level enhancement at Earth. The ground level enhancement on the …

Ground level enhancements (GLEs) are extreme solar energetic particle (SEP) events that
are of particular importance in space weather. In solar cycle 24, two GLEs were recorded on …

A series of coronal mass ejections (CMEs) erupted from the same active region between 4–
6 September 2017. Later, on 6–9 September, two interplanetary (IP) shocks reached L1 …

Solar flares are sudden eruption of intense high-energy radiation from the Sun causing radio
perturbations due to disturbances in ionosphere and magnetosphere of the Earth. The …
