Excerpt from The Sun's Spotted Area, 1832 1900: A Statement of the Mean Daily Area in Each Synodic Rotation of the Sun, Based Upon Data Collected at the Solar Physics Observatory, South Kensington
The published results of the reductions of solar photographs which have been made at Greenwich since 1873 include the mean daily areas for each year and for each synodic rotation, the latter being especially valuable in investigations for which a year is too great a unit of time. Similar data are also given by De la Rue in his manuscript reductions of the Kew series of photographs (1862 to and for this reason it has been decided to adopt a synodic rotation as the unit of time in constructing a new curve on the basis of spotted area. This curve has already been in use for some time at the Solar Physics Observatory, and it is thought that, together with the figures on which it is based, it may prove useful to other workers. The areas throughout are expressed in millionths of the sun's visible hemisphere.
