Doppler measurements, using the Capri magnetograph, of the latitudinal fine structure of the solar differential rotation have been carried out. The positions of...
Effect of Gravity on the Fast Modes of a Horizontal Coronal Slab
Theoretical studies of the normal modes of a coronal slab often neglect gravity, as in Edwin and Roberts ( Solar Phys. 71, 239, 1982). Here we study...
Evidence of a White-Light Flare on 10 September 1886
We present evidence of the occurrence of a white-light flare on 10 September 1886. It represents the third such rare event reported in the history of astronomy...
Evolution of the Fine Structure of Magnetic Fields in the Quiet Sun: Observations from Sunrise/IMaX and Extrapolations
Observations with the balloon-borne Sunrise/ Imaging Magnetograph eXperiment (IMaX) provide high spatial resolution (roughly 100 km at disk center) measurements...
Phase diversity techniques are robust post-processing tools for image enhancement and correction of telescopic and atmospheric induced aberrations. We present...
The GOLF experiment on the SOHO mission aims to study the internal structure of the Sun by measuring the spectrum of global oscillations in the frequency range...
