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…
Probabilistic Drag-Based Ensemble Model (DBEM) Evaluation for Heliospheric Propagation of CMEs
Jaša Čalogović, Mateja Dumbović, Davor Sudar +4
The Drag-based Model (DBM) is a 2D analytical model for heliospheric propagation of Coronal Mass Ejections (CMEs) in ecliptic plane predicting the CME arrival time and speed at Ear…
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…
Space weather: the solar perspective -- an update to Schwenn (2006)
Manuela Temmer
The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary space and affect planetary atmospheres. The effects of Space Weather on Earth and the…
Drag-based model (DBM) tools for forecast of coronal mass ejection arrival time and speed
Mateja Dumbovic, Jasa Calogovic, Karmen Martinic +4
Forecasting the arrival time of CMEs and their associated shocks is one of the key aspects of space weather research. One of the commonly used models is, due to its simplicity and…
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…
Why are ELEvoHI CME arrival predictions different if based on STEREO-A or STEREO-B heliospheric imager observations?
Jürgen Hinterreiter, Tanja Amerstorfer, Martin A. Reiss +9
Accurate forecasting of the arrival time and arrival speed of coronal mass ejections (CMEs) is a unsolved problem in space weather research. In this study, a comparison of the pred…
