| Zusammenfassung |
| Sensitive spectropolarimetric observations from the Haleakala SOLARC
coronagraph and infrared imaging spectropolarimeter have detected an
extended diffuse surface brightness flux at the 1083nm wavelength of
neutral helium (He I). This has the polarization signature of light
scattered by an extended He I cloud in the vicinity of the Sun. A series
of observations obtained during the last two years suggest that this
signal originates from an "inner source" of neutral helium atoms in the
solar corona. |
