Revising the Sunspot Number

“AZleader” writes at “Inform the pundits”. Austin, August 16, 2014 – A rare spotless day on the sun on July 17-18, 2014 triggered public speculation that an already stunted Cycle 24 was nearly over. Such is not the case. Defying the odds for so late in a sunspot cycle, another solar sunspot maximum was set…

A Gleissberg Solar Minimum?

Allan MacRae says: Thanks to Alberta Jacobs In a recent paper “The Centennial Gleissberg Cycle and its Association with Extended Minima”, to be soon published in JGR/Space, Feynman and Ruzmaikin discuss how the recent extended minimum of solar and geomagnetic variability (XSM) mirrors the XSMs in the 19th and 20th centuries: 1810–1830 and 1900–1910.
