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.
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.
A sunspot minimum is a period in the solar cycle when the Sun has fewer sunspots than usual. This is part of an 11-year cycle of solar activity, where the Sun goes through periods of high and low sunspot activity. During a sunspot minimum, the Sun appears quieter with less magnetic activity on its surface.
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.
The greatest number of sunspots during the period of 1700 to 1800 occurred during the mid-18th century, around the 1760s. This period is known as the "Maunder Minimum," where sunspot activity was very low for an extended period of time.
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.Paraphrased from:http://www.windows.ucar.edu/tour/link=/sun/sun_climate.html
The Maunder Minimum was created in 1976.

Maunder minimum
The Maunder Minimum, a period of low solar activity in the 17th century, is linked to a cooler climate known as the "Little Ice Age." Some scientists suggest that understanding past solar variations like the Maunder Minimum can help improve climate change models and predictions.

The mechanisms behind the lack of sunspots in the late 16 hundreds to the early 17 hundreds (the Maunder Minimum) is debated. Among the effects on the Earth was colder weather for extended periods of time (the canals in the Netherlands froze solid each winter for decades), this has only happened occasionally during the last century.
