Scientific paper
We report on the first successful simultaneous polarimetric measurements of the brightness of the Thompson-scattered white light and intensity of the near-infrared Fe XIII 10747 Å line, the strongest of the coronal iron forbidden lines. These observations which extended out to 3 Rs in the corona were obtained during the total solar eclipse of 21 June 2001. The novel technique used to acquire these measurements will be presented. Polarized intensity measurements of the resonantly scattered component of coronal emission lines are the only tools to date that can yield the direction of the coronal magnetic field. Through these simultaneous measurements, we show how the direction of the coronal magnetic field can be placed in the context of coronal density structures. We also discuss the implications of these simultaneous measurements for the source of the solar wind.
