Extreme Red-wing Enhancements of UV Lines During the 2022 March 30 X1.3 Solar Flare
Yan Xu, Graham S. Kerr, Vanessa Polito +3
Here we present the study of a compact emission source during an X1.3 flare on 2022-March-30. Within a ~s period (17:34:48 UT to 17:35:29 UT), IRIS observations show spectr…
Multi-instrument Comparative Study of Temperature, Number Density, and Emission Measure during the Precursor Phase of a Solar Flare
Nian Liu, Ju Jing, Yan Xu +1
We present a multi-instrument study of the two precursor brightenings prior to the M6.5 flare (SOL2015-06-22T18:23) in the NOAA Active Region 12371, with a focus on the temperature…
A Comparative Study of Solar Active Region 12371 with Data-constrained and Data-driven MHD Simulations
Satoshi Inoue, Keiji Hayashi, Takahiro Miyoshi +2
We performed two data-based magnetohydrodynamic (MHD) simulations for solar active region 12371 which produced an M6.5 flare. The first simulation is a full data-driven simulation…
Solar Flare Index Prediction Using SDO/HMI Vector Magnetic Data Products with Statistical and Machine Learning Methods
Hewei Zhang, Qin Li, Yanxing Yang +4
Solar flares, especially the M- and X-class flares, are often associated with coronal mass ejections (CMEs). They are the most important sources of space weather effects, that can…
Multi-Passband Observations of A Solar Flare over the He I 10830 Å line
Yan Xu, Xu Yang, Graham S. Kerr +5
This study presents a C3.0 flare observed by the BBSO/GST and IRIS, on 2018-May-28 around 17:10 UT. The Near Infrared Imaging Spectropolarimeter (NIRIS) of GST was set to spectral…
Development of Technique to Detect and Classify Small-Scale Magnetic Flux Cancellation and Rapid Blueshifted Excursions
Xin Chen, Na Deng, Derek A. Lamb +5
We present a set of tools for detecting small-scale solar magnetic cancellations and the disk counterpart of type II spicules (the so-called Rapid Blueshifted Excursions (RBEs)), u…
