A nonlinear solar magnetic field calibration method for the filter-based magnetograph by the residual network
Jingjing Guo, Xianyong Bai, Yuanyong Deng +5
The method of solar magnetic field calibration for the filter-based magnetograph is normally the linear calibration method under weak-field approximation that cannot generate the s…
Observation of solar coronal heating powered by magneto-acoustic oscillations in a moss region
Parida Hashim, Zhenxiang Hong, Haisheng Ji +3
In this paper, we report the observed temporal correlation between extreme-violet (EUV) emission and magneto-acoustic oscillations in a EUV moss region, which is the footpoint regi…
Temporal and Periodic Variation of the MCMESI for the Last Two Solar Cycles; Comparison with the Number of Different Class X-Ray Solar Flares
A. Kilcik, P. Chowdhury, V. Sarp +4
In this study we compared the temporal and periodic variations of the Maximum CME Speed Index (MCMESI) and the number of different class (C, M, and X) solar X-Ray flares for the la…
Strong Blue Asymmetry in Hα line as a Preflare Activity
Kyuhyoun Cho, Jeongwoo Lee, Jongchul Chae +5
Chromospheric activities prior to solar flares provide important clues to solar flare initiation, but are as yet poorly understood. We report a significant and rapid H line broa…
Rapid Evolution of Type II Spicules Observed in Goode Solar Telescope On-Disk H-alpha Images
Vasyl Yurchyshyn, Wenda Cao, Valentina Abramenko +2
We analyze ground-based chromospheric data acquired at a high temporal cadence of 2 s in wings of the H spectral line using Goode Solar Telescope (GST) operating at the Big Bear…
Spatial Distribution of Origin of Umbral Waves in a Sunspot Umbra
Vasyl Yurchyshyn, Ali Kilcik, Seray Sahin +2
Umbral flashes (UFs) are emissions in the core of chromospheric lines caused by upward propagating waves steepening into shocks. UFs are followed by an expanding blue shifted umbra…
