Hermann Wahn reported on the astronomical observations of Jupiter's moons and sunspots in the Hamburg state calendar .

The astronomer Johann Elert Bode wrote in 1823 that Johann Georg Büsch had proposed in 1770 that the “Steerenkiker-Huus” be retained as an observatory for the city of Hamburg, but that this failed because of the resistance of the house owner.
