An Airborne Coronal Emission Surveyor (ACES) for Solar Eclipse Observations

AbstractUsing the eclipse observations, we construct the maps of quiescent prominence temperatures, electron densities, pressures and geometrical thicknesses. For this we use the RGB signal of prominence visible-light emission detected during the total solar eclipse on August 1, 2008 in Mongolia, and quasi-simultaneous Hα spectra taken at Ondřejov observatory. The method of disentangling the electron density and effective geometrical thickness was described by Jejčič & Heinzel (2009) and is used here for the first time to analyse the spatial variations of various prominence parameters.

The results are presented of ionosphere measurements made in the region of totality during the eclipse of July 9, 1945. An analysis of the results shows effective recombination coefficients of 1.6 × 10−8 for E region, 1.4 × 10−8 for F1 region, and 1.0 × 10−9 for F2 region. Evidence of a variable coefficient for E region agrees with the suggestion of Massey and others of a high negative ion density at this level.

Eclipse Observations

Ground-based total solar eclipse observations are still the key method for coronal investigations. The question about its white-light degree of polarization remains unanswered. There are hypotheses claiming that the degree of polarization in certain regions of the corona may be higher than the maximal theoretically predicted value determined by Thomson scattering. We present polarization of the white-light solar corona observations obtained by three different teams during the March 29, 2006 solar total eclipse. We give an interpretation on how the polarization of the sky impacts brightness of the polarized solar corona, depending on the landscape during the totality. Moreover, it is shown that the singular polarization points of the corona are in linear dependence with the height of the Sun above the horizon.
