An Optical Magnetometer Used at Kyoto University

Caption

A Japanese team have digitalized magnetogram recordings taken before direct observations by satellites became available. The analog recordings, taken for 72 years since the early 20th century, provide a window onto space weather in the mid-1900s and shed light onto future patterns of plasma movement in near-earth space.
