Scientists predict a new solar cycle is about to begin and that it will be stronger than the last one
Powerful eruption from the surface of the sun captured on May 1, 2013. By Joe Kunches April 11 at 10:29 AM The latest 11-year cycle of the sun is almost over and scientists have just released predictions for the next one.
Lisa Upton, a solar physicist with Space Systems Research Corporation and co-chair of the panel issuing predictions, said Cycle 25 should begin between mid-2019 and late 2020 and that it should reach its maximum between 2023 and 2026, when between 95 and 130 sunspots are projected. Average is between 140 and 220 sunspots.
The decline in sunspot activity through cycle 24 was worrisome to some space weather scientists in that it suggested a return to a lengthy “solar drought,” reminiscent of the Maunder Minimum period of 1645-1715. Records show the sun was essentially spotless for this lengthy period, coinciding with the “Little Ice Age” in Europe and tickling the interest of scientists to wonder whether there is a cause-and-effect relationship between solar behavior and Earth’s climate.
The prediction of solar cycle behavior is very difficult. “We are not really ‘there’ on the underlying physics of the problem. It’s a bit like pin the tail on the donkey,” McIntosh said.
