  Maunder, Edward Walter (1851-1928)
Maunder's appointment allowed Greenwich to branch out from purely positional work, for Maunder began a careful study of the Sun, mainly of sunspots and related phenomena.
In 1893 Maunder, while checking the solar cycle in the past, came across the surprising fact that between 1645 and 1715 there was virtually no sunspot activity at all.
Maunder also played a significant part in the debate on the canals of Mars by carrying out experiments with marked circular disks and concluding, as did Simon Newcomb, that the canals "are simply the integration by the eye of minute details too small to be separately and distinctly defined."

 Sunspot K-12 Experiments for Lesson Plans & Science Fair Projects
During the Maunder Minimum there were hardly any sunspots at all and the earth may have cooled by up to 1°C.
Edward Maunder would later suggest a period over which the Sun had changed modality from a period in which sunspots all but disappeared from the solar surface, followed by the appearance of sunspot cycles starting in 1700.
Sunspot research was dormant for much of the 17th and early 18th centuries because of the Maunder Minimum, during which no sunspots were visible for some years; but after the resumption of sunspot activity, Heinrich Schwabe in 1843 reported a periodic change in the number of sunspots.

 17th century solar oddity believed linked to global cooling is rare among nearby stars
The drop in solar activity in the late 17th and early 18th centuries was drawn to the world's attention in 1893 by English astronomer Edward Walter Maunder, who also noted a dip during the same period in the intensity and frequency of the northern lights, which are caused by storms on the sun.
The idea of a Maunder minimum is controversial, however, because no one really knows how closely people were observing the sun in the mid-1600s, a mere 40 years after the invention of the telescope.
The problem with stars thought to be in a Maunder minimum went unnoticed because it wasn't until 1998 that the Hipparcos satellite was launched and began determining the precise distances to many nearby stars.

 Science Fair Projects - Edward Walter Maunder
Part of his job involved photographing and measuring sunspots, and in doing so he observed that the solar latitudes at which sunspots occur varies in a regular way over the course of the 11 year cycle.
After 1891, he was assisted in his work by his second wife, Annie Scott Dill Maunder (neé Russell), a mathematician educated at Cambridge University.
After studying the work of Gustav Spoerer, who had identified a period from 1400 to 1510 when sunspots had been rare ("the Spoerer Minimum"), he examined old records from the observatory's archives to determine whether there were other such periods.

The period was identified by the English astronomer edward walter maunder by searching through old records.
Maunder contradicted this idea by showing that in the recent past solar behavior had departed dramatically from the regular cycle, and he was ignored.
Since the Spörer and Maunder minima were recognized other, similar episodes have been identified, as well as sunspot maxima, when there were more sunspots than usual.

 Astronomy - Solar funk - Pamela Zerbinos
This solar funk, which has not been repeated, came to be called the "Maunder minimum," and it coincided with the coldest part of the Little Ice Age in Europe and North America.
Maunder also noticed a dip in the frequency and intensity of the northern lights — which are caused by solar storms — during that same period.
A decrease in the calcium emission of a Sun-like star, therefore, should be evidence of a star in a period of inactivity.

 Features and Events
Maunder saw that Sporer was right: firsthand reports of solar observations noted not one spot on the sun's northern hemisphere between 1672 and 1704.
Maunder wrote to Andrew Douglass who was measuring tree ring growth patterns to learn if there was any connection between ring patterns and the sunspot cycle.
After much study, Eddy was convinced that Maunder had been correct all along, and he dubbed the period of solar inactivity the "Maunder Minimum".

 06.01.2004 - Was 17th century solar funk a rarity?
Characterized by colder than normal winters and cool summers throughout the Northern Hemisphere, it may have been caused by greenhouse gases and particulates spewed into the atmosphere by volcanoes, or by fluctuations in the sun's output.
Solar activity is characterized by strong magnetic fields that heat the sun's upper atmosphere, or chromosphere, to some 8,000 to 10,000 degrees Kelvin, exciting calcium to emit blue light.
He noted that some of the stars previously identified as Maunder minimum stars may be metal-rich stars, which also burn brighter than our sun and show less activity.

Apparent references to sunspots were made by Chinese astronomers in 28 BC, who probably could see the largest spot groups when the sun's glare was filtered by wind-borne dust from the various central Asian deserts.
Gustav Spörer later suggested a 70-year period before 1716 in which sunspots were rarely observed as the reason for Wolf's inability to extend the cycles into the seventeenth century.
Even the lack of a solar corona during lunar eclipses was noted prior to 1715.

Edward Walter Maunder, Assistant at the Royal Observatory (1873-1919).
Edward Walter Maunder worked as an assistant at the Observatory from 1873 to 1913, and again from 1915 to 1919.
With his wife Annie, he collected data on sunspots, from which they concluded that sunspots went in cycles (as demonstrated in Maunder’s famous butterfly diagrams) and these cycles could be linked to magnetic disturbances and changes in weather.

 Lowell, Percival (1855-1916)
Meanwhile, his colleague at Lick, Edward Barnard, one of the most respected observers of his day, scrutinized the Martian surface with the giant 36-inch refractor but failed to see any sign of straight narrow lines.
Lowell countered by arguing that large telescopes were ill-suited to planetary observation and, in any case, much depended on the seeing conditions which, he asserted, at Flagstaff were among the best available.
Then the mystery markings would suddenly stand out, he said: "like the lines in a fine steel etching." Also in 1894, Edward Maunder, in England, suggested that the canals might be optical illusions and did some experiments with model disks to prove his point.
