Quasi-Periodic Pulsations Detected in Ly alpha and Nonthermal Emissions During Solar Flares

期刊: SOLAR PHYSICS, 2021; 296 (8)

We report quasi-periodic pulsations (QPPs) with double periods during three solar flares (viz. SOL2011-Feb-15T01:44, SOL2011-Sep-25T04:31, SOL2012-May......

Energy Partition in Four Confined Circular-Ribbon Flares

期刊: SOLAR PHYSICS, 2021; 296 (4)

In this study, we investigate the energy partition of four confined circular-ribbon flares (CRFs) that occurred close to solar disk center. The flares......

Occurrence Rate of Radio-Loud and Halo CMEs in Solar Cycle 25: Prediction Using their Correlation with the Sunspot Number

期刊: SOLAR PHYSICS, 2021; 296 (4)

Solar coronal mass ejections (CMEs) are known for their space-weather and geomagnetic consequences. Among all CMEs, the so-called radio-loud (RL) and ......

Resonant Damping of Kink Modes in Solar Coronal Slabs

期刊: SOLAR PHYSICS, 2021; 296 (6)

We examine resonantly damped kink modes in straight coronal slabs, paying special attention to the effects of the formulation for the transverse densi......

Solar Cycle Dependence of ICME Composition

期刊: SOLAR PHYSICS, 2021; 296 (7)

Coronal mass ejections (CMEs) belong to the most energetic explosions in the solar atmosphere, and their occurrence rates exhibit obvious solar cycle ......

A Dynamo-Based Prediction of Solar Cycle 25

期刊: SOLAR PHYSICS, 2021; 296 (9)

The solar activity cycle varies in amplitude. The last Solar Cycle 24 is the weakest in the past century. Sun's activity dominates Earth's space envir......

Critical Science Plan for the Daniel K. Inouye Solar Telescope (DKIST)

期刊: SOLAR PHYSICS, 2021; 296 (4)

The National Science Foundation's Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand, and model the basic ......

Predicting Sunspot Numbers Based on Inverse Number and Intelligent Fixed Point

期刊: SOLAR PHYSICS, 2021; 296 (5)

This article proposes a new model for predicting sunspot activity based on the inverse number and intelligent fixed point. Firstly, in the training ph......

Dependence of Great Geomagnetic Storm (Delta SYM-H <=-200 nT) on Associated Solar Wind Parameters

期刊: SOLAR PHYSICS, 2021; 296 (4)

We use Delta SYM-H to capture the variation in the SYM-H index during the main phase of a geomagnetic storm. We define great geomagnetic storms as tho......

The Fengyun-3E/Joint Total Solar Irradiance Absolute Radiometer: Instrument Design, Characterization, and Calibration

期刊: SOLAR PHYSICS, 2021; 296 (3)

The Joint Total Solar Irradiance Monitor (JTSIM) is due to fly onboard the Fengyun-3E spacecraft and aims to measure the Total Solar Irradiance (TSI) ......

Upflows in the Upper Solar Atmosphere Invited Review

期刊: SOLAR PHYSICS, 2021; 296 (3)

Spectroscopic observations at extreme- and far-ultraviolet wavelengths have revealed systematic upflows in the solar transition region and corona. The......

Image Desaturation for SDO/AIA Using Deep Learning

期刊: SOLAR PHYSICS, 2021; 296 (3)

The Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) (launched in February 2010) provides uninterrupted full-disk sola......

Statistical and Solar Cycle Distribution of Daily Flux >=<mml:msup>109</mml:msup><mml:msup> cm-2</mml:msup>d(-1)sr(-1) for E > 2 MeV Electrons Observed by GOES During 1987-2019

期刊: SOLAR PHYSICS, 2021; 296 (1)

We studied the statistical and solar cycle distribution of daily flux &gt;= 109 cm-2d(-1)sr(-1) for E&gt;2 MeV electrons Observed by GOES from 1987 to......

Population of Bright Plume Threads in Solar Polar Coronal Holes

期刊: SOLAR PHYSICS, 2021; 296 (1)

Coronal holes are well accepted to be source regions of the fast solar wind. As one of the common structures in coronal holes, coronal plumes might co......

New Vacuum Solar Telescope Fringe Removal Based on "Fringes Flat Field"

期刊: SOLAR PHYSICS, 2021; 296 (1)

The solar chromosphere data products of the New Vacuum Solar Telescope (NVST) have been affected by the interference fringes since its first operation......
