Deciphering Solar Magnetic Activity: Spotting Solar Cycle 25
We present observational signatures of solar cycle 25 onset. Those signatures are visibly following a migratory path from high to low latitudes. They had starting points that are asymmetrically offset in each hemisphere at times that are 21–22 years after the corresponding, same polarity, activity bands of solar cycle 23 started their migration. Those bands define the so-called “extended solar ...
متن کاملThe Solar Cycle
The solar cycle is reviewed. The 11-year cycle of solar activity is characterized by the rise and fall in the numbers and surface area of sunspots. A number of other solar activity indicators also vary in association with the sunspots including; the 10.7 cm radio flux, the total solar irradiance, the magnetic field, flares and coronal mass ejections, geomagnetic activity, galactic cosmic ray fl...
متن کاملSolar Cycle Prediction
A review of solar cycle prediction methods and their performance is given, including forecasts for cycle 24. The review focuses on those aspects of the solar cycle prediction problem that have a bearing on dynamo theory. The scope of the review is further restricted to the issue of predicting the amplitude (and optionally the epoch) of an upcoming solar maximum no later than right after the sta...
متن کاملIrradiance and solar cycle variability: clues in cycle phase properties
We see solar cycle-related variations in almost every coronal, chromospheric, and photospheric measurement obtained over a several-years timescale. With such an abundant observational foundation, we should expect our physical models of the solar cycle to be overconstrained. In fact this is not the case and the ‘‘standard dynamo model’’ is not predictive. This paper describes some new thoughts o...
