Aug 18, 2020 interest in stealth coronal mass ejections (cmes) is increasing due to we present an extensive study of the magnetic field configuration in surface (pfss ) model, and complemented by in-depth observational analysis.
Three proposed observational tests are discussed on how to establish the correct coronal magnetic filaments l: the roll effect in erupting prominences.
Aug 1, 2018 observatories will help explain why the corona is so hot and what drives the and in recent years, satellites and suborbital rockets, observing above magnetic fields on the far side of the sun and test whether monit.
Observations have indicated that magnetic reconnect ion may occur frequently in the photosphere and chromosphere as well as in the solar corona.
Oct 17, 2007 observational test of coronal magnetic field models.
The simplicity of the geometry of polar plumes makes them an ideal test ground for the study of magnetohydrodynamic (mhd) wave interaction with solar coronal structures. The review covers recent observational findings of compressible and incompressible waves in polar plumes with imaging and spectral instruments, and interpretation of the waves.
The coronal magnetic reconnection hypothesis can explain the observations via the notion that superflares and solar flares share the same origin and that the two activity distributions therefore.
Observational tests of damping by resonant absorption in coronal loop of the density ratio ne/ni is also required to calculate a coronal magnetic field.
Like coronal mass ejections, it is from the corona which the solar wind is expelled at velocities that allow it to escape the gravitational pull of the star and stream outward in all directions.
The study of geomagnetism is one of the oldest of the geophysical sciences. Geomagnetic fields have been observed and used since ancient times.
The estimated coronal magnetic field can be checked against features inferred from in microwave, euv, and x-ray coronal observations, as well as from h(x observations (levine 1975). Coordinated observing campaigns of active regions, such as the comstoc series, can significantly improve our understanding of the nature of coronal magnetic fields.
To measure properties of the coronal magnetic fields and test models of coronal heating flux tubes, the building blocks of stellar magnetic fields observations have established that the photospheric magnetic field is organized in small fibrils or flux tubes.

This is the first time that a global map of the coronal magnetic field has been obtained through actual coronal observations, thus marking a leap towards solving the problem of coronal magnetic.
More than 20 years ago, a technique called coronal seismology or magnetoseismology was introduced for coronal magnetic field diagnostics.
Together with the linear polarization measurements that map the azimuthal direction of the coronal magnetic field projected in the plane of the sky containing sun center, these coronal vector magnetograms allow for direct and quantitative observational testing of theoretical coronal magnetic field models.
Coronal holes theoretical/modeling definition: regions with magnetic fields “open” to heliosphere. Observation definition: regions of low emission in the solar corona. Coronal holes are important because they are a major source of the solar wind and thus help link the sun-heliosphere system coronal hole potential field source surface (pfss.
