The Solar Cycle [PDF]

Advances in Astronomy, 2012
The ~11-year solar cycle was first identified in the fluctuation of the number and location of sunspots and, soon after, their magnetic polarity and the dipole component of the Sun’s magnetism as a whole. The cycle is manifested in satellite records of total and variable solar luminosity, in the open solar magnetic flux, which can be estimated from ...

Detailed understanding of reduced geoeffectiveness of solar cycle 24 in association with geomagnetic storms

Frontiers in Astronomy and Space Sciences
Solar Cycle 24, the weakest in over a century, exhibited significant deviations from previous cycles, beginning with a prolonged minimum, weak polar fields, and asynchronous polar field reversal, leading to hemispheric asymmetry.
