Journal ArticleDOI
Sunspot Bright Rings: Evidence from Case Studies
TL;DR: In this article, a ring of enhanced continuum intensity surrounding large isolated sunspots was found to be about 0.5-1.0% brighter in red and blue continuum (10 K warmer) than the surrounding photosphere and extend about one sunspot radius outward from the outer penumbral boundary.
Journal ArticleDOI
The Seismology of Sunspots: A Comparison of Time-Distance and Frequency-Wavenumber Methods*
TL;DR: In this article, a pair of formulae are developed that relate the absorption coefficient and partial wave phase shift concepts of frequency-wavenumber local helioseismology to the center-annulus cross-correlation function of time-distance heliosesismology, under the general circumstances that both induced and spontaneous sunspot oscillations may be present.
Journal ArticleDOI
Weak-Field Magnetogram Calibration using Advanced Stokes Polarimeter Flux-Density Maps – I. Solar Optical Universal Polarimeter Calibration
T.E. Berger,Bruce W. Lites +1 more
TL;DR: In this paper, the authors compare the performance of the SOUP and ASP magnetograms in terms of their polarity sensitivity to the minority polarity structures relative to the ASP magnetogram.
Journal ArticleDOI
High-speed photospheric material flow observed at the polarity inversion line of a δ-type sunspot producing an X5.4 flare on 2012 March 7
TL;DR: In this paper, high-speed material flow was observed along the polarity inversion line located between flare ribbons at the main energy release side of an X5.4 flare on 7 March 2012.
Journal ArticleDOI
Remote sensing of solar magnetic fields
TL;DR: In this article, a review of the state-of-the-art techniques for remote sensing of solar magnetic fields is presented, along with an assessment of how future improvements in observing capabilities will address these requirements.
