Solar Coronal Holes: Spectra, Solar Spectrum: Helium Lines

Scientific paper

The authors obtained a batch of 2-dimensional He I 10830 spectra of solar polar areas. Preliminary analysis shows that some He I 10830 "dark points" and coronal holes were recorded. The observations of May 8, 1995, are briefly described. It is found that in the He I 10830 spectroheliograms there exist dark structures on a scale of 10″- 20″whose absorption depths are 10% - 20%. On the velocity image deduced from two off-band He I 10830±0.14 Å images, blueshifts are remarkably seen in those dark points. They also notice that in some local regions, the He I 10830 absorption obviously decreases and the chromospheric networks are relatively unclear, indicating the regions are coronal holes.
