Scientists predict sun’s activity will be weak during next solar cycle

(8. April 2019)

„We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak cycle, preceded by a long, deep minimum,“ said panel co-chair Lisa Upton, Ph.D., solar physicist with Space Systems Research Corp. „The expectation that Cycle 25 will be comparable in size to Cycle 24 means that the steady decline in solar cycle amplitude, seen from cycles 21-24, has come to an end and that there is no indication that we are currently approaching a Maunder-type minimum in solar activity.“

Scientists predict a new solar cycle is about to begin and that it might be stronger than the last one

(11. April 2019)

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 Sun Is Turning Blank And We’re Not Quite Sure Why

(3.5.2018) We do know the Sun goes through variations, so there’s nothing to be too worried about. But it is quite unusual, especially as we’re not even really sure what causes solar cycles. Maybe the Sun is just taking some well-deserved time off. After 4.6 billion years, who could blame it?
