A coronal mass ejection encountered by four spacecraft within 1 au from the Sun: ensemble modelling of propagation and magnetic structure
Al-Haddad, Nada; Riley, Pete; Richter, Ingo +11 more
Understanding and predicting the structure and evolution of coronal mass ejections (CMEs) in the heliosphere remains one of the most sought-after goals in heliophysics and space weather research. A powerful tool for improving current knowledge and capabilities consists of multispacecraft observations of the same event, which take place when two or…
Hemispheric asymmetry of coronal bright point's number and area over solar cycles 23-24
Karachik, Nina V.; Minenko, Ekaterina P.
Temporal variations in the number and area of coronal bright points (CBPs) were studied separately in the Northern and Southern hemispheres over more than two solar cycles (years 1996-2022). Hemispheric asymmetry was identified in both the total number and area of CBPs, with differences reaching up to 15 per cent. Statistical analysis using Studen…
