people who study the sun said that solar flares happens approximately every 11 years. some are small. 93 million miles away... an angry sun vents its rage. Dark regions, called sunspots, appeared unexpectedly on its surface... a sign of rising tension within. It had been three and a half years since the sun last erupted in fury...at the peak of an 11-year cycle of solar flare-ups.

A solar eruption in 1859 was so powerful it set fire to telegraph offices... several people got nasty electric shocks, simply because they were working with metal objects... and for the next few nights, auroras were reportedly bright enough to read by.

This 11 year cycle is part of a larger 22 year magnetic cycle in the sun where the polarity of magnetic field lines switch causing the flares. It is said every 11 years because that is when the North and South poles of the sun switch, but it takes another 11 years on top of that before they revert back.

How often does the sun's poles flip?

The sun's magnetic poles flip approximately every 11 years, coinciding with the sunspot cycle. This phenomenon is known as solar magnetic field reversal.


Sunspots are most numerous in the sun in solar maximum or solar minimum?

Sunspots are most numerous during solar maximum, which occurs approximately every 11 years. During solar minimum, the sun is less active and sunspot activity decreases.

How often does the sunspot cycle repeat itself?

The sunspot cycle typically repeats approximately every 11 years, though the length can vary from about 9 to 14 years. This cycle is characterized by the waxing and waning of sunspot activity on the Sun's surface.


What happens every 823 years?

There is an internet hoax going around claiming that certain occurrences of five days in a month occur every 823 years. For examples, in October 2010, there were five Fridays, Saturdays, and Sundays. However, this occurrence occurs at the most every 11 years. The next time five Fridays, Saturdays, and Sundays occurs in a month is March 2013. The next time it occurs in October is October 2021.


What changes in 11-year cycles?

Solar activity, such as sunspots and solar flares, follows an 11-year cycle known as the solar cycle. This cycle is driven by changes in the sun's magnetic field and can affect space weather and geomagnetic activity on Earth.


What years did 25 December fall on a Wednesday?

To determine the years when December 25th fell on a Wednesday, we need to understand the concept of the Gregorian calendar. December 25th falls on a Wednesday every 6-11 years, following a pattern known as the Gregorian cycle. The years when this occurs are 2019, 2024, 2030, 2041, 2047, 2052, and so on, with a recurring cycle every 11 years.


What years did November 1 fall on a Wednesday?

November 1 fell on a Wednesday in the years 2006, 2017, and 2023. This pattern occurs approximately every 11 years due to the way the calendar progresses. To find future occurrences, you can continue to add 11 or 6 years to these years, adjusting for leap years as necessary.
