Transactions of the International Astronomical Union, 1982 This report summarizes research on solar activity over an almost three-year period from January 1, 1979, till the end of June 1981. In preparing this report we respected the advice of the I.A.U. Executive Committee to cover the highlights of work carried out in the field of solar physics relevant to our Commission, and avoiding double work.

Eos, Transactions American Geophysical Union, 1991 Perhaps the most newsworthy item of recent times concerning solar activity is its unprecedented strength during the rising phase of its current 11‐year cycle. Examples of its potency include a major, well‐observed solar flare in March 1989 that launched an unusually powerful blast wave that, hitting Earth, caused spectacular low‐latitude auroras and ...

The onset of solar cycle 24: What global acoustic modes are telling us
, 2009 We study the response of the low-degree, solar p-mode frequencies to the unusually extended minimum of solar surface activity since 2007. A total of 4768 days of observations collected by the space-based, Sun-as-a-star helioseismic GOLF instrument are ...

The Magnetic Field in the Solar Atmosphere [PDF]
, 2014 This publication provides an overview of magnetic fields in the solar atmosphere with the focus lying on the corona. The solar magnetic field couples the solar interior with the visible surface of the Sun and with its atmosphere.
