The text discusses the recent findings related to the sun's cycles, particularly the Gleissberg Cycle, which lasts about 100 years and affects sunspot activity. New research published in the journal Space Weather indicates that the Gleissberg Cycle is beginning to wake up after a low phase lasting around 15 years. This change may result in increasingly intense solar cycles over the next 50 years.
The researchers, led by Kalvyn Adams, an astrophysics student, studied protons in the South Atlantic Anomaly, a weak area in Earth's magnetic field. They found that a decrease in these protons serves as a signal that the Gleissberg Cycle is about to become more active. Their measurements show a decline in proton counts, aligning with rising sunspot numbers, increased ultraviolet output from the sun, and heightened solar activity in the current Solar Cycle 25. These signs suggest that the Gleissberg Minimum has ended, which was believed to have contributed to the weak Solar Cycle 24.
The anticipated increase in solar activity in the coming cycles, particularly Solar Cycles 26 through 28, may lead to significantly more intense solar conditions, with Solar Cycle 26 expected to peak around 2036. The peak of the Gleissberg Cycle is projected around 2055, coinciding with Solar Cycle 28, which could be very strong. As space activity and satellite launches increase, it will be crucial to prepare for changes in the space environment due to more solar activity and particle fluxes in the future.
