Deciphering Solar Magnetic Activity: 140 Years Of The `Extended Solar Cycle' -- Mapping the Hale Cycle
Scott W. McIntosh, Robert J. Leamon, Ricky Egeland +6
We investigate the occurrence of the "extended solar cycle" (ESC) as it occurs in a host observational data spanning 140 years. Investigating coronal, chromospheric, photospheric a…
Overlapping Magnetic Activity Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude
Scott W. McIntosh, Sandra C. Chapman, Robert J. Leamon +2
The Sun exhibits a well-observed modulation in the number of spots on its disk over a period of about 11 years. From the dawn of modern observational astronomy sunspots have presen…
Solar Wind Helium Abundance Heralds Solar Cycle Onset
B. L. Alterman, Justin C. Kasper, Robert J. Leamon +1
We study the solar wind helium-to-hydrogen abundance's () relationship to solar cycle onset. Using OMNI/Lo data, we show that increases prior to suns…
