Validation scheme for solar coronal models -- constraints from multi-perspective observations in EUV and white-light
A. Wagner, E. Asvestari, M. Temmer +2
Context: In this paper we present a validation scheme to investigate the quality of coronal magnetic field models, which is based upon comparisons with observational data from mult…
How to Estimate the Far-Side Open Flux using STEREO Coronal Holes
Stephan G. Heinemann, Manuela Temmer, Stefan J. Hofmeister +3
Global magnetic field models use as input synoptic data, which usually show "aging effects" as the longitudinal 360° information is not obtained simultaneously. Especially during t…
Multi-channel coronal hole detection with convolutional neural networks
R. Jarolim, A. M. Veronig, S. Hofmeister +4
We develop a reliable, fully automatic method for the detection of coronal holes, that provides consistent full-disk segmentation maps over the full solar cycle and can perform in…
Coronal Hole Detection and Open Magnetic Flux
J. A. Linker, S. G. Heinemann, M. Temmer +14
Many scientists use coronal hole (CH) detections to infer open magnetic flux. Detection techniques differ in the areas that they assign as open, and may obtain different values for…
Statistical Approach on Differential EmissionMeasure of Coronal Holes using the CATCH Catalog
Stephan G. Heinemann, Jonas Saqri, Astrid M. Veronig +2
Coronal holes are large-scale structures in the solar atmosphere that feature a reduced temperature and density in comparison to the surrounding quiet Sun and are usually associate…
Properties of stream interaction regions at Earth and Mars during the declining phase of SC 24
Paul Geyer, Manuela Temmer, Jingnan Guo +1
We inspect the evolution of SIRs from Earth to Mars (distance range 1-1.5 AU) over the declining phase of solar cycle 24 (2014-2018). So far, studies only analyzed SIRs measured at…
