Commission 10: Solar Activity
Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, microflares, nanoflares, coronal heating etc., which are all manifestation of the interplay of magnetic fields and solar plasma. Increasingly important is the study of solar ...
متن کاملAllais gravity and pendulum effects during solar eclipses explained
Gravitational and other anomalies seen repeatedly in connection with solar eclipses have led to speculation about a possible gravitational shielding effect as the cause. Here we show that an unusual phenomenon that occurs only during solar eclipses, rapid air mass movement for the bulk of the atmosphere above normal cloud levels, appears to be a sufficient explanation for both the magnitude and...
متن کاملVisibility of stars, halos, and rainbows during solar eclipses.
The visibility of stars, planets, diffraction coronas, halos, and rainbows during the partial and total phases of a solar eclipse is studied. The limiting magnitude during various stages of the partial phase is presented. The sky radiance during totality with respect to noneclipse conditions is revisited and found to be typically 1/4000. The corresponding limiting magnitude is +3.5. At totality...
متن کاملSearch for Possible Solar Neutrino Radiative Decays during Total Solar Eclipses
Total solar eclipses (TSEs) offer a good opportunity to look for photons produced in possible radiative decays of solar neutrinos. In this paper we briefly review the physics bases of such searches as well as the existing limits for the ν2 and ν3 proper lifetimes obtained by such experiments. We then report on the observations performed in occasion of the 29 March 2006 TSE, from Waw an Namos, L...
متن کاملRendering lunar eclipses
Johannes Kepler first attributed the visibility of lunar eclipses to refraction in the Earth’s atmosphere in his Astronomiae Pars Optica in 1604. We describe a method for rendering images of lunar eclipses including color contributions due to refraction, dispersion, and scattering in the Earth’s atmosphere. We present an efficient model of refraction and scattering in the atmosphere, including ...
