Maunder MinimumA period of unusually low sunspot activity taken from visual accounts of the number of sunspots observed on the solar disk. Of interest is that the sun has 11 and 22 year solar activity cycles and this period was a deviation from this frequency pattern. This 11 year variation of solar energy reaching the earth has been sited to effect a tropospheric temperature variation in the order of .5 to 1 of a degree. The Maunder Minimum of sustain low solar activity has been sited as a possible trigger for the 'Mini Ice Age' cross Europe and North America.

What is a sunspot minimum?
a sunspot minimum (also known as maunder minimum) is the name used for the period roughly spanning 1645 to 1715 when sunspots exceedingly became rare as noted by solar observers of the time.
What is the Maunder minimum?
The Maunder Minimum, also known as the "prolonged sunspot minimum", is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.
What is a Maunder object?
A "Manunder Object" could be a sunspot occurring during the Maunder Minimum. The Maunder Minimum is the name given to the period roughly spanning 1645 to 1715 by John A. Eddy in a landmark 1976 paper published in Science titled "The Maunder Minimum", when sunspots became exceedingly rare, as noted by solar observers of the time. Astronomers before Eddy had also named the period after the solar astronomer Edward W. Maunder (1851-1928) who studied how sunspot latitudes changed with time.
How do you describe the sunspots cycle?
Over a span of about 11 years, the face of the Sun changes. At the low point of the cycle, the Sun may have no sunspots (dark, somewhat cooler areas on the surface of the Sun) or a few sunspots. As the cycle progresses, more sunspots, and larger more active sunspots will appear, until the "Solar Max" at which time the Sun has many, sometimes dozens of spots. The Sun is likely to be more active with more and stronger solar flares. Then the Sun begins to quiet down, and back to being "blank". The whole cycle generally takes about 11 years, but it can be as little as 9 or as long as 13 years. There have been speculations that the sunspot cycle may be associated with changes in the climate, that when sunspots are abundant, the weather is a bit warmer, and that when sunspots are rare, the climate is cooler. The extremes of this phenomenon so far have been two extended periods (70 and 40 years) with almost no sunspots at all. From 1645 to 1715 (back at the dawn of sunspot observation) astronomers observed very few sunspots. In the 1880's, two astronomers named Maunder correlated the period of very few sunspots with a period of unusually cold weather, and later scientists named this period the Maunder Minimum. A later period of very low sunspot numbers called the Dalton Minimum (1790-1830) is correlated with unusually cold weather as well. We're not sure what the connection is between cool weather and low sunspot numbers, or even if this is really a "connection"; "Once is happenstance, twice is coincidence, three times is enemy action", goes the old saying. There has not yet been a third period of low sunspots AND cold weather to correllate.
How might Earth be affected by the activity of sunspots on the surface of the sun?
We're not sure why, but when there are very few sunspots during the 11-year "sunspot cycle", or when that cycle slows down, we experience colder than usual weather here on Earth. We've only been tracking sunspots for about 400 years; before then, nobody knew to look for them, or were able to. The sunspot cycle which began last year is Cycle 24. There have been two extended periods of few or no sunspots; one was the Maunder Minimum, from 1645 to 1715, and the Dalton Minimum, from 1790 to 1830. The Maunder Minimum coincides with a period known as the "Little Ice Age", and during the Dalton Minimum the recorded temperatures were perhaps 2-3 degrees below normal. Periods of increased sunspot activities appear to be associated with slightly higher than normal temperatures.

What did Walter maunder discover about sunspot activity in 1893?
came across the surprising fact that between 1645 and 1715 there was virtually no sunspot activity at all.
What is a sunspot minimum?
a sunspot minimum (also known as maunder minimum) is the name used for the period roughly spanning 1645 to 1715 when sunspots exceedingly became rare as noted by solar observers of the time.
What did Voltaire call the period between 1661 and 1715?
Voltaire called the period between 1661 and 1715 the "Age of Louis XIV". This time was characterized by the reign of King Louis XIV of France, known for his centralized power, cultural achievements, and military conquests. Voltaire admired and critiqued the era for its grandeur and influence.
What is the Maunder minimum?
The Maunder Minimum, also known as the "prolonged sunspot minimum", is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.

How long did the rococo period last?
Roughly from 1715 till the French revolution.
What is 15 percent of 1715?
15% of 1715= 15% * 1715= 0.15 * 1715= 257.25

When did Louis XIV become King?
He reigned from 1643 until 1715. He became the King at the age of 4, had his coronation in 1654 at the age of 15.
What date did the dodo bird extinct?
Scientists estimate it was some time between 1688 and 1715.
