Solar jet-coronal hole collision and a related coronal mass ejection [PDF]

, 2016
Jets are defined as impulsive, well-collimated upflows, occurring in different layers of the solar atmosphere with different scales. Their relationship with coronal mass ejections (CMEs), another type of solar impulsive events, remains elusive. Using the high-quality imaging data of AIA/SDO, here we show a well-observed coronal jet event, in which part

How Did Westward Volcaniclastic Deposits Accumulate in the Deep Sea Following the January 2022 Eruption of Hunga Volcano?

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Most volcanic eruptions on Earth take place below the ocean surface and remain largely unobserved. Reconstruction of past submerged eruptions has thus primarily been based on the study of seafloor deposits. Rarely before the 15 January 2022 eruption of Hunga volcano (Kingdom of Tonga) have we been able to categorically link deep‐sea deposits ...

The Magnetic Topology of AR13664 Leading to Its First Halo CME

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract In the first half of May 2024, the solar active region (AR) NOAA 13664 was responsible for generating the strongest geomagnetic storm in over 20 years through an enhanced production of coronal mass ejections (CMEs). A key factor in this production was the complex magnetic topology of AR13664.

Midlatitude Neutral Wind Response During the Mother's Day Super‐Intense Geomagnetic Storm in 2024 Using Observations From the Chinese Meridian Project

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Using new observations from the Chinese Meridian Project (CMP), this study examines the characteristics of neutral winds in the East Asian sector during the Mother's Day super‐intense storm in May 2024, primarily focusing on its effects on the disturbances over China and adjacent areas.

A probabilistic approach to the drag-based model

Journal of Space Weather and Space Climate, 2018
The forecast of the time of arrival (ToA) of a coronal mass ejection (CME) to Earth is of critical importance for our high-technology society and for any future manned exploration of the Solar System. As critical as the forecast accuracy is the knowledge

Detecting coronal mass ejections with machine learning methods [PDF]

Proc. IAU 19 (2023) 404-408
Flares on the Sun are often associated with ejected plasma: these events are known as coronal mass ejections (CMEs). These events, although are studied in detail on the Sun, have only a few dozen known examples on other stars, mainly detected using the Doppler-shifted absorption/emission features in Balmer lines and tedious manual analysis.

Magnetically Quiet‐Time Traveling Ionospheric Disturbances Over Mid‐Latitude Eastern Europe Observed by the Kharkiv Incoherent Scatter Radar During the 24th Solar Cycle

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract We have detected and characterize traveling ionospheric disturbances (TIDs) in the mid‐latitude ionosphere over Europe using data from the Kharkiv incoherent scatter (IS) radar. The study focused on observations near solstices and equinoxes during solar cycle 24 under magnetically quiet conditions.

Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach

The Astrophysical Journal
Identifying the source regions of coronal mass ejections (CMEs) is crucial for understanding their origins and improving space weather forecasting. We present an automated algorithm for matching CMEs detected by the Large Angle Spectrometric Coronagraph ...
