Solar Eruptions, Forbush Decreases and Geomagnetic Disturbances from Outstanding Active Region 12673
I. M. Chertok, A. V. Belov, A. A. Abunin
Based on our tool for the early diagnostics of solar eruption geoeffectiveness (EDSEG tool; Chertok et al., 2013, 2015, 2017), we have analyzed space weather disturbances that occu…
Segmentation of coronal holes in solar disk images with a convolutional neural network
E. Illarionov, A. Tlatov
Current coronal holes segmentation methods typically rely on image thresholding and require non-trivial image pre- and post-processing. We have trained a neural network that accura…
Tilt of sunspot bipoles in Solar Cycles 15 to 24
Ksenia Tlatova, Andrey Tlatov, Alexei Pevtsov +7
We use recently digitized sunspot drawings from Mount Wilson Observatory to investigate the latitudinal dependence of tilt angles of active regions and its change with solar cycle.…
Long-Term Oscillations of Sunspots and a Special Class of Artifacts in SOHO(MDI) and SDO(HMI) Data
V. I. Efremov, A. A. Soloviev, L. D. Parfinenko +6
A specific type of artifacts, that originate due to displacement of the image of a moving object along the digital (pixel) matrix of receiver are analyzed in detail. The criteria o…
