Generic profile of a long-lived corotating interaction region and associated recurrent Forbush decrease
Mateja Dumbovic, Bojan Vrsnak, Manuela Temmer +2
We observe and analyse a long-lived corotating interaction region (CIR), originating from a single coronal hole (CH), recurring in 27 consecutive Carrington rotations 2057-2083 in…
First year of energetic particle measurements in the inner heliosphere with Solar Orbiter's Energetic Particle Detector
R. F. Wimmer-Schweingruber, N. Janitzek, D. Pacheco +45
Solar Orbiter strives to unveil how the Sun controls and shapes the heliosphere and fills it with energetic particle radiation. To this end, its Energetic Particle Detector (EPD) h…
First Solar energetic particles measured on the Lunar far-side
Zigong Xu, Jingnan Guo, Robert. F. Wimmer-Schweingruber +6
On 2019 May 6, the Lunar Lander Neutron & Dosimetry (LND) Experiment on board the Chang'E-4 on the far-side of the Moon detected its first small solar energetic particle (SEP) even…
Evolution of coronal mass ejections and the corresponding Forbush decreases: modelling vs multi-spacecraft observations
Mateja Dumbović, Bojan Vršnak, Jingnan Guo +9
One of the very common in situ signatures of interplanetary coronal mass ejections (ICMEs), as well as other interplanetary transients, are Forbush decreases (FDs), i.e. short-term…
Statistical results for solar energetic electron spectra observed over 12 years with STEREO/SEPT
Nina Dresing, Frederic Effenberger, Raul Gomez-Herrero +5
We present a statistical analysis of near-relativistic (NR) solar energetic electron event spectra near 1au. We use measurements of the STEREO Solar Electron and Proton Telescope (…
Seed Population Pre-Conditioning and Acceleration Observed by Parker Solar Probe
N. A. Schwadron, S. Bale, J. Bonnell +42
A series of solar energetic particle (SEP) events were observed at Parker Solar Probe (PSP) by the Integrated Science Investigation of the Sun (\ISOIS) during the period from April…
An Analytical Diffusion-Expansion Model for Forbush Decreases Caused by Flux Ropes
Mateja Dumbović, Bernd Heber, Bojan Vršnak +2
We present an analytical diffusion-expansion Forbush decrease (FD) model ForbMod which is based on the widely used approach of the initially empty, closed magnetic structure (i.e.…
The Dependence of the Peak Velocity of High-Speed Solar Wind Streams as Measured in the Ecliptic by ACE and the STEREO satellites on the Area and Co-Latitude of their Solar Source Coronal Holes
Stefan J. Hofmeister, Astrid Veronig, Manuela Temmer +3
We study the properties of 115 coronal holes in the time-range from 2010/08 to 2017/03, the peak velocities of the corresponding high-speed streams as measured in the ecliptic at 1…
The Solar Electron and Proton Telescope aboard STEREO -- understanding proton spectra
S. Wraase, B. Heber, S. Böttcher +3
The Solar Electron and Proton Telescope (SEPT) aboard the Solar Terrestrial Relations Observatory (STEREO) is designed to provide the three-dimensional distribution of energetic el…
Characteristics of Low-Latitude Coronal Holes near the Maximum of Solar cycle 24
S. J. Hofmeister, A. Veronig, M. A. Reiss +4
We investigate the statistics of 288 low-latitude coronal holes extracted from SDO/AIA-193 filtergrams over the time range 2011/01/01 to 2013/12/31. We analyse the distribution of…
Modulation of galactic cosmic rays during the unusual solar minimum between cycles 23 and 24
L. -L. Zhao, G. Qin, M. Zhang +1
During the recent solar minimum between cycles 23 and 24 (solar minimum ) the intensity of Galactic Cosmic Rays (GCRs) measured at the Earth was the highest ever recorde…
Earth-Affecting Solar Causes Observatory (EASCO): A mission at the Sun-Earth L5
Nat Gopalswamy, Joseph M. Davila, Frédéric Auchère +11
Coronal mass ejections (CMEs) and corotating interaction regions (CIRs) as well as their source regions are important because of their space weather consequences. The current under…
