Abstract

The balloon flights were performed during the solar rotations 1792 to 1795 of which following relevant features are represented in Figs. 1-4:
  • the Zürich relative sunspot numbers (CRPL Boulder reports),

  • the position of plage regions on which flares occurred (CRPL Boulder reports),

  • the duration of balloon flights at Kiruna, marked by rectangular boxes, whereby the letter X above a box means that X-rays were measured during these flights,

  • the duration of balloon flights at other stations,

  • 3-hourly planetary amplitudes ap (by courtesy of Geophysikalisches Institut, Univers. Göttingen),

  • hourly neutron counting rates at Deep-River (CRPL Boulder reports).
