Deciphering solar magnetic activity: The (solar) hale cycle terminator of 2021

Frontiers in Astronomy and Space Sciences, 2023
We previously identified an event in the solar timeline that appeared to play a role in how sunspot Cycle 23 (SC23) transitioned into sunspot Cycle 24 (SC24). The timeframe for this transition was rapid, taking place over a very short time and perhaps in

Solar Extreme and Far Ultraviolet Radiation Modeling for Aeronomic Calculations

Remote Sensing, 2021
Modeling the upper atmosphere and ionospheres on the basis of a mathematical description of physical processes requires knowledge of ultraviolet radiation fluxes from the Sun as an integral part of the model.

About the Foroughi Cup and about the seven planets in the Ancient World [PDF]

Archaeoastronomy and Ancient Technologies, 2018
The Foroughi Cup is an artefact of the 8th century BC of Aramaic cultural context, inside which images of stars and constellations are reproduced. In this study of ours we start from the conclusions reached by Amadasi Guzzo and Castellani in their two ...
