What is Maunder Minimum in astronomy?
Maunder minimum, unexplained period of drastically reduced sunspot activity that occurred between 1645 and 1715. Astronomers such as John Flamsteed and Gian Domenico Cassini who did observe sunspots during that period noted that they were the first they had seen in years.
What was the Maunder Minimum and what is its significance for the study of Earth’s climate?
The Maunder Minimum occurred within the Little Ice Age, a long period of lower-than-average European temperatures. The reduced solar activity may have contributed to the climatic cooling, although the cooling began before the solar minimum and its primary cause is believed to be volcanic activity.
Who discovered Maunder Minimum?
The Maunder Minimum was named by solar astronomer John Eddy in 1976 after E.W. Maunder, an English scientist who, along with German scientist Gustav Spörer, first noticed the decrease in solar activity in the 1890s, according to the New York Times.
What is the Maunder maximum?
Solar maximum is the regular period of greatest solar activity during the Sun’s 11-year solar cycle….Solar minimum events and approximate dates.
| Event | Start | End |
|---|---|---|
| Medieval maximum (see Medieval Warm Period) | 1100 | 1250 |
| Wolf minimum | 1280 | 1350 |
| Spörer Minimum | 1450 | 1550 |
| Maunder Minimum | 1645 | 1715 |
What is the Maunder Minimum why is it of interest?
The existence of the Maunder minimum is interesting on purely astrophysical grounds, because it suggests that the regular rise and fall of sunspots observed from 1715 all the way through to the present day may not be a permanent, or even typical, aspect of solar behavior.
What effects did the Maunder Minimum have on Earth?
Since during the Maunder Minimum the Sun emitted less radiation, in total, including strong ultraviolet emission, less ozone was formed affecting planetary atmosphere waves, the giant wiggles in the jet stream. Shindell et al. [4. Solar forcing of regional climate change during the Maunder minimum.
What was the possible impact of the Maunder Minimum on Earth?
During the Maunder Minimum, the Sun emitted less strong ultraviolet light, and so less ozone formed. The decrease in ozone affected planetary waves, the giant wiggles in the jet stream that we are used to seeing on television weather reports.
What is Maunder famous for?
Edward Walter Maunder (1851–1928) was a British astronomer who devoted his academic career to the study of sunspots and the solar magnetic cycle. He is known for the discovery of a conspicuous solar calm that lasted from 1645 to 1715 that was named the Maunder Minimum.
