Radial Evolution of the April 2020 Stealth Coronal Mass Ejection between 0.8 and 1 AU -- A Comparison of Forbush Decreases at Solar Orbiter and Earth
Johan L. Freiherr von Forstner, Mateja Dumbović, Christian Möstl +40
Aims. We present observations of the first coronal mass ejection (CME) observed at the Solar Orbiter spacecraft on April 19, 2020, and the associated Forbush decrease (FD) measured…
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…
Long- and Mid-Term Variations of the Soft X-ray Flare Type in Solar Cycles
I. M. Chertok, A. V. Belov
Using data from the Geostationary Operational Environmental Satellites (GOES) spacecraft in the 1-8 Å wavelength range for Solar Cycles 23, 24, and part of Cycles 21 and 22, we com…
Cosmic Rays near Proxima Centauri b
Alexei Struminsky, Andrei Sadovski, Anatoly Belov
Cosmic rays are an important factor of space weather determining radiation conditions near the Earth and it seems to be essential to clarify radiation conditions near extrasolar pl…
A Simple Way to Estimate the Soft X-ray Class of Far-Side Solar Flares Observed with STEREO/EUVI
I. M. Chertok, A. V. Belov, V. V. Grechnev
Around the peaks of substantial flares, bright artifact nearly horizontal saturation streaks (B-streaks) corresponding to the brightest parts of the flare sources appear in the STE…
Relationship between the Magnetic Flux of Solar Eruptions and the Ap Index of Geomagnetic Storms
I. M. Chertok, M. A. Abunina, A. A. Abunin +2
Solar coronal mass ejections (CMEs) are main drivers of the most powerful non-recurrent geomagnetic storms. In the extreme-ultraviolet range, CMEs are accompanied by bright post-er…
A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. IV. Unusual Magnetic Cloud and Overall Scenario
V. V. Grechnev, A. M. Uralov, I. M. Chertok +4
The geomagnetic superstorm of 20 November 2003 with Dst = -422 nT, one of the most intense in history, is not well understood. The superstorm was caused by a moderate solar eruptiv…
Magnetic Flux of EUV Arcade and Dimming Regions as a Relevant Parameter for Early Diagnostics of Solar Eruptions - Sources of Non-Recurrent Geomagnetic Storms and Forbush Decreases
I. M. Chertok, V. V. Grechnev, A. V. Belov +1
This study aims at the early diagnostics of geoeffectiveness of coronal mass ejections (CMEs) from quantitative parameters of the accompanying EUV dimming and arcade events. We stu…
A new version of the Neutron Monitor Based Anisotropic GLE Model : Application to GLE60
C. Plainaki, H. Mavromichalaki, A. Belov +3
In this work we present a cosmic ray model that couples primary solar cosmic rays at the top of the Earth's atmosphere with the secondary ones detected at ground level by neutron m…
