Abstract: | Observations of 121 occurrences of the aurora borealis recorded in Central Europe from 1645 to 1712 C.E. are compared with known phase relationships between auroral activity and sunspot cycles in modern times. A remarkable analogy of the aurora borealis cycles during the Maunder minimum is found, both with respect to phase-dependent frequency and to delayed maxima, with aurorae during the 19th and 20th centuries. |
