Many astronomers have been surprised by the sudden increase in solar activity since the beginning of this year. We have witnessed a large number of solar flare eruptions, including multiple X-class flares, we have even seen G4-class geomagnetic storms hit Earth and solar winds have been moving extraordinarily fast. This was unusual because the peak of the ongoing Solar Cycle 25 was calculated to be in mid-2025, and by that standard, many feared this Solar Maximum could be one of the most intense ones on record. However, a new study has now claimed that the peak could arrive as soon as this year itself. This would mean that solar storms are going to get a lot more intense.
As per a report by SpaceWeather.com, a group of solar physicists published their research in the January 2023 edition of Frontiers in Astronomy and Space Sciences. The study is based on the work of researchers around a relatively new concept in solar physics known as Termination Event. As per the study, the peak of Solar Cycle 25, which is also known as Solar Maximum, can arrive either by the end of 2023 or the middle of 2024.
As per SpaceWeather, “The "Termination Event" is a relatively new concept in solar physics. It is a period of time on the sun as short as one month when magnetic fields from one solar cycle abruptly die (they are "terminated") allowing magnetic fields from the next solar cycle to take over”.
The team of researchers studied many solar cycles to gain a better understanding of Termination Event and their finding was surprising. They found that by knowing the precise timing of one Termination Event, it is possible to find the time for the next one. “Our latest work pinpoints the Termination Event between Solar Cycle 24 and Solar Cycle 25
