Nomenclature

According to the [/IAU%20Planetary%20Gazetteer IAU Planetary Gazetteer], the name honors a husband and wife, both British astronomers:
- Annie Scott Dill Russell Maunder (1868-1947), born in Ireland, collaborated with her husband, "Walter," especially in the investigation of historic sunspot records. She was the first woman elected to the Royal Astronomical Society.
- Edward Walter Maunder (1851-1928), born in London, served at the Royal Observatory, Greenwich, where, in collaboration with his second wife, Annie, he was the first to plot sunspot records in the form of the now-familiar "butterfly diagram." They also noted a possible correlation between sunspot activity and Earth's climate, including a period of low activity and cold weather much later referred to as the "Maunder Minimum."
Although Maunder appears in the cumulative list of approved names in [/IAU%20Transactions%20XVB IAU Transactions XVB], it is not clear precisely when and where it was approved. Judging from its longitude, the name may have been introduced in the [/Rectified%20Lunar%20Atlas Rectified Lunar Atlas], but it is not included in the changes reported and approved in [/IAU%20Transactions%20XIIB IAU Transactions XIIB]. - JimMosher JimMosher
