description Annie Russell Maunder Overview
Annie Russell Maunder was an Irish-British astronomer known for her contributions to solar observation and sunspot research. Working at the Royal Greenwich Observatory, she developed the 1904 butterfly diagram, which plots sunspot latitudes over time to reveal their migration pattern during solar cycles. She was an accomplished astronomical photographer who documented solar eclipses and collaborated with her husband, Edward Walter Maunder, on studying the Sun's long-term behavior, including the period of low sunspot activity now known as the Maunder Minimum.
help Annie Russell Maunder FAQ
What is Annie Russell Maunder known for?
Annie Russell Maunder was an Irish-British astronomer known for solar observation and sunspot research. She worked at the Royal Greenwich Observatory.
What is the butterfly diagram associated with Annie Maunder?
The butterfly diagram plots sunspot latitudes over time. Maunder developed the diagram in 1904 to show how sunspots migrate toward the solar equator during a solar cycle.
Did Annie Maunder work at the Royal Greenwich Observatory?
Yes. Her astronomical work was connected with the Royal Greenwich Observatory, where she contributed to systematic solar observation.
Why are sunspot observations scientifically useful?
Sunspots trace changing magnetic activity on the Sun. Their latitude patterns help astronomers study the roughly repeating solar cycle.
