Non-Spot Magnetic Fields,uch a field. Today, the term general magnetic field is often used interchangeably with polar field. The problem of determining the existence of a true general magnetic field is that of eliminating the effect of transient magnetic fields which collect near the poles. See polar field and large scale magnetic field.

Prominences,eir greater density than their coronal surroundings and by temperatures ranging from about 10. K to coronal values at the interface to the corona. They appear as bright (cool and dense) features (in the corona) above the solar limb; when seen projected against the solar disk nearly all prominences show up in absorption as ..

General Theoretical Terms,f refractive index. This anomalous dispersion is particularly important in the analysis of lines formed in the presence of a magnetic field. The differently split components of the line have different dispersions which leads to a rotation of the axes of the polarization ellipse as the radiation traverses the medium.

Quiet Photosphere and Chromosphere,he quiet Sun are that the overall pattern of its fine structures is statistically uniform and/or stationary, that there is no (conspicuous) enhancement or reduction of radiation and that there is no extended magnetic flux concentration (see Figure 3.3). Only at very low resolution (≳l0″) does the quiet Sun really appear quiet.

Active Regions,ce of a certain (transient) phenomenon (e.g. flare activity, surge activity, X-ray activity) or the occurrence of ‘active regions’ (‘solar activity’ in general). Radio activity, for example, can imply both the occurrence of radio bursts and the longer-lasting enhancement of radio emission.

Spots and Faculae, the weak photospheric network. The faculae are cospatial with bright plages observed in chromospheric lines (H Balmer lines, Ca II lines, He II 304 Å) and transition region lines, and with regions of enhanced magnetic fields.

Flares and Associated Phenomena,article or high energy flare). The temperatures attained in the chromosphere are ≈ 10. K (chromospheric or low temperature flare), in the corona ≈ 10. K (high temperature flare). The energies of observed particles range from 20 keV up to ≈ 1 GeV. The total energy released in the largest events is ≈ 10. erg.
